Nanosensors and printed electronics integration in future lab on a chip biose...Daniel Thomas
The cardiovascular disease (CVD) is now a major threat to global health, particularly in the Western hemisphere. There is a growing demand for a range of portable, rapid and low cost biosensing devices for the detection of CVD.
Biosensors can play an important role in the early diagnosis of CVD without having to rely on hospital visits where expensive and time-consuming laboratory tests are recommended. Over the last decade, many biosensors have been developed to detect a wide range of cardiac markers to reduce the costs of healthcare.
Recently, the prevention and treatment of hepatitis C virus (HCV) complications consider as major obstacles to reducing HCV outbreaks worldwide. Therefore, it is crucial to develop a new alternative therapy for HCV infection with low cost and low side effects. A smart device termed a Life Restoration Device (LRD) was designated to produce a low potential codified amount of ions. The specified codified amount of ions produced from LRD are designated to exterminate HCV. To investigate our hypothesis, we designated an experimental system for in-vitro studies. This system is composed of a glass tube that can be filled with HCV polymerase chain reaction (PCR)-positive serum. The result of this study showed that LRD can decrease the viral load of HCV PCR-positive serum to 99% after 2 hrs treatment. The viral load reduction of the LRD against low HCV PCR count was almost similar to that of high HCV PCR count. Furthermore, the efficacy of LRD to reduce the serum viral load after 30 min or 60 min treatment was 74%or 95% respectively while the viral load after2 hrs treatment was about 91%. The electron microscopy investigation of HCV PCR-positive serum after treatment with LRD showed degenerated HCV particles compared with the non-treated virus. The in vitro treatment of the HCV PCR-positive serum with LRD didn’t affect the blood contents such as red blood cells count, white blood cells count and hemoglobin levels. The sincerity of the codified amount of ions produced by LRD may affect the fragile fluidity of the viral envelope. Treatment of hepatitis viruses with a codified amount of ions is a new alternative therapy but needs more studies. It is crucial to develop an effective alternative viral therapy using such kind of technology to reduce the antiviral drugs side effects.
Design of MEMS Biosensor for Pathogenic Bacterial Disease DetectionAI Publications
In situations of a critical disease outbreak, any time delay in identifying the pathogen can prove to be risky and has its far-reaching effects on public health systems. There is a need for pathogenic bacteria detection at the point‐of‐care (POC) using a fast, sensitive, inexpensive, and easy‐to‐use method that does not require complex infrastructure and well‐trained technicians. For instance, detection of pneumonia, tuberculosis at acute infection stage has been challenging, since current antibody‐based POC technologies are not effective due to low concentration of antibodies. In this study, we demonstrated for the first time a label‐free electrical sensing method that can detect pathogenic bacteria, through MEMS cantilever technology. The presented method offers a rapid and portable tool that is MEMS biosensor, can be used as a bacteria detection technology at the hospital and primary care settings.
For many years scientists yearned for the possibility of performing flow cytometry to analyse small bio-nanoparticles that are too small to be measured by conventional and high sensitivity instruments. These entities, extracellular vesicles, gene therapy vectors, viruses and drug delivery particles, are promised to become the next generation of therapeutics, but they have been hard to handle and characterise due to their small size and biological or chemical heterogeneity. There is therefore a strong case for bringing flow cytometry capability to the sub-200nm scale.
NanoFCM has developed the NanoAnalyzer platform that now enables true flow-cytometry measurement at the sub-micron scale, and down to particle sizes unreachable by any other flow cytometers (10-40nm depending on the nature of the substrate). Nano-flow cytometry, the technology that underpins the NanoAnalyzer, removes bias and uncertainty stemming from the use of fluorescence signal triggering by using its highly sensitive side-scatter channel to trigger particle events. The single-particle nature of the measurement prevents uncontrolled swarming events, reinforcing data integrity. High resolution of both scatter and fluorescence channels allows the assessment of subpopulations, based on size or on bio-chemical properties.
Nano-flow cytometry’s ability to measure simultaneously a (bio)-nanoparticle population for size, size distribution and bio-chemical properties on a single instrument dramatically improves data quality and throughput compared to the traditional, multiple-techniques approach involving particle characterisation and counting (DLS, NTA, RPS), combined with chemical and biological function assessment (ELISA, Western Blot, Flow Cytometry, PCR). Quantitative measurement of the active and contaminant particles in a single preparation opens up the possibility of characterisation-based nanomedicine regulatory approval, and allows the conduct of large-scale clinical studies. From the research laboratory to the quality control department, NanoFCM delivers comprehensive bio-nano analysis.

Membranes, or phospholipid bilayers, which are electrical insulators, build a hydrophobic, low dielectric barrier to hydrophilic and charged molecules. Ion channels are a sort of membrane protein complexes. Their function is to facilitate the diffusion of ions across biological membranes. Ion channels provide a high conducting, hydrophilic pathway across the hydrophobic interior of the membrane. Ion channels act as gateways which allow ions to travel through them to respond to multiple signal events.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Electrochemical immunosensor
1.
2. Introduction
Detection of anti-hepatitis C virus (anti-HCV)
antibodies
May yield a high frequency of false-positive results in
people at low risk
According to World Health Organization estimations,
3. Anti-HCVantibody can not distinguish between a
current or past infection because people will retain
anti-HCV antibodies for life once they are exposed
to HCV. In addition, testing anti-HCV antibody
might provide false negative results because it ta kes
45– -68 days to develop ant i-HCV antibody post HCV
infection .
4. On the other hand, detection of HCV RNA can distinguish
betweena current or past infection. However, d etection of
HCV RNA could
prov ide false positive results due to contamination.
It is also expensive and labor-intensive for routine use.
5. Electrochemical immunosensor
Based on the highly specific molecular
recognition of antigen by its antibodies, have ahigh
interest in clinical diagnostics and will be expected
to provide fast and highly sensitive detection of HCV
core antigencore antigen based on our knowledge
The advantages of excellent sensiti vity, rapid response
and cost-effectiveness of the nanostructured metaloxides
make them the preferable choices to fabricate biosensor
6. We report on the construction of a label-free electrochemical
immunosensor for detecting the core antigen of the
hepatitis C virus (HCV core antigen). A glassy carbon
electrode (GCE) was modified with a nanocomposite made
from gold nanoparticles, zirconia nanoparticles and
chitosan, and prepared by in situ reduction.
The zirconia nanoparticles were first dispersed in chitosan
solution, and then AuNPs were prepared in situ on the
ZrO2-chitosan composite. In parallel, a nanocomposite was
synthesized from AuNPs, silica nanoparticles and chitosan,
and conjugated to a secondary antibody.
7. The properties of the resulting nanocomposites were
investigated by UV-visible photometry and
transmission electron microscopy, and the stepwise
assembly process was characterized by means of cyclic
voltammetry and electrochemical impedance
spectroscopy.
8. The advantages of excellent sensiti vity, rapid response
and cost-effectiveness of the nanostructured metal
oxides
make them the preferable choices to fabricate biosensor
We developed a novel and reliable procedure to construct
in one-step procedure using a chitsosan as reducing agent.
Anti-HCV was immobilized on this nanocomposite to
fabricate the immunosensor. The secondary antib ody
was immobilized on AuNPs/SiO2-Chit s nanocomposite,
which enhanced signal response of the HCV
immunosensor An sandwich type of immunosensor was
developed which displays high sensitivity to the HCV core
antigen in the concentration range between 2 and
512 ng mL−1, with a detection limit of 0.17 ng mL−1 (at
S/N = 3). This immunosensor provides an alternative
approach towards the diagnosis of HCV.
9. A sandwich-type immunosensor was constructed for the detection of
HCV core Ag. AuNPs/ZrO2-Chits nanocomposites were prepared by in
situ reduction method. AuNPs/SiO2-Chits nanocomposite integrated
with secondary antibody (Ab2) without labeled HRP. The immunosensor
displayed high sensitivity to HCV core antigen with a detection limit of
0.17 ng mL−1 (S/N = 3).
