A biosensor is an analytical device which converts a biological response into an electrical signal. The term biosensor is often used to cover sensor devices used in order to determine the concentration of substances and other parameters of biological interest even where they do not utilize a biological system directly. Biosensors have become essential analytical tools, since they offer higher performance in terms of sensitivity and selectivity than any other currently available diagnostic tool. With appropriate progress in research, biosensors will have an important impact on environmental monitoring, reducing cost and increasing efficiency. Biosensors represent a rapidly expanding field, at the present time, with an estimated 60% annual growth rate; where major focus is on health care industry. Although there use is unquestionable in the field of agri food, research, security and defence. In this paper various aspects of biosensors have been touched.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.

Biosensors
1. A biosensor is a device that measures biological or chemical reactions by generating
signals proportional to the concentration of an analyte in the reaction. Biosensors are
employed in applications such as disease monitoring, drug discovery, and detection of
pollutants, disease-causing micro-organisms and markers that are indicators of a disease
Biosensors
pollutants, disease-causing micro-organisms and markers that are indicators of a disease
in bodily fluids (blood, urine, saliva, sweat).
2. Consists of the following components:
• Analyte: A substance of interest that needs detection. For instance, glucose is an ‘analyte’ in a
biosensor designed to detect glucose.
• Bioreceptor: A molecule that specifically recognises the analyte is known as a bioreceptor. Enzymes,
cells, aptamers, deoxyribonucleic acid (DNA) and antibodies are some examples of bioreceptors. The
process of signal generation (in the form of light, heat, pH, charge or mass change, etc.) upon interaction
of the bioreceptor with the analyte is termed bio-recognition.
• Transducer: The transducer is an element that converts one formof energy into another. In a
biosensor the role of the transducer is to convert the bio-recognition event into a measurable signal. This
process of energy conversion is known as signalisation. Most transducers produce either optical orprocess of energy conversion is known as signalisation. Most transducers produce either optical or
electrical signals that are usually proportional to the amount of analyte–bioreceptor interactions.
• Electronics: This is the part of a biosensor that processes the transduced signal and prepares it for
display. It consists of complex electronic circuitry that performs signal conditioning such as amplification
and conversion of signals from analogue into the digital form. The processed signals are then
quantified by the display unit of the biosensor.
• Display: The display consists of a user interpretation system such as the liquid crystal display of a
computer or a direct printer that generates numbers or curves understandable by the user. This part
often consists of a combination of hardware and software that generates results of the biosensor in a
user-friendly manner. The output signal on the display can be numeric, graphic, tabular or an image,
depending on the requirements of the end user.

5. Characteristics of a biosensor
There are certain static and dynamic attributes that every biosensor possesses. The optimisation
of these properties is reflected on the performance of the biosensor.
Selectivity
Selectivity is perhaps the most important feature of a biosensor. Selectivity is the ability of a
bioreceptor to detect a specific analyte in a sample containing other admixtures and
contaminants. The best example of selectivity is depicted by the interaction of an antigen with
the antibody. Classically, antibodies act as bioreceptors and are immobilised on the surface of
the transducer. A solution (usually a buffer containing salts) containing the antigen is then
exposed to the transducer where antibodies interact only with the antigens. To construct a
biosensor, selectivity is the main consideration when choosing bioreceptors.biosensor, selectivity is the main consideration when choosing bioreceptors.
Reproducibility
Reproducibility is the ability of the biosensor to generate identical responses for a duplicated
experimental set-up. The reproducibility is characterised by the precision and accuracy of the
transducer and electronics in a biosensor. Precision is the ability of the sensor to provide alike
results every time a sample is measured and accuracy indicates the sensor’s capacity to provide
a mean value close to the true value when a sample is measured more than once. Reproducible
signals provide high reliability and robustness to the inference made on the response of a
biosensor.
6. Stability
Stability is the degree of susceptibility to ambient disturbances in and around the biosensing
system. These disturbances can cause a drift in the output signals of a biosensor under
measurement. This can cause an error in the measured concentration and can affect the
precision and accuracy of the biosensor. Stability is the most crucial feature in applications
where a biosensor requires long incubation steps or continuous monitoring. The response of
transducers and electronics can be temperature-sensitive, whichmay influence the stability
of a biosensor. Therefore, appropriate tuning of electronics is required to ensure a stable
response of the sensor. Another factor that can influence the stability is the affinity of theresponse of the sensor. Another factor that can influence the stability is the affinity of the
bioreceptor, which is the degree to which the analyte binds to the bioreceptor. Bioreceptors
with high affinities encourage either strong electrostatic bonding or covalent linkage of the
analyte that fortifies the stability of a biosensor. Another factor that affects the stability of
ameasurement is the degradation of the bioreceptor over a period of time.
7. Sensitivity
The minimum amount of analyte that can be detected by a biosensor defines its limit of
detection (LOD) or sensitivity. In a number of medical and environmental monitoring
applications, a biosensor is required to detect analyte concentration of as low as ng/ml or
even fg/ml to confirmthe presence of traces of analytes in a sample. For instance, a
prostate-specific antigen (PSA) concentration of 4 ng/ml in blood is associated with prostate
cancer for which doctors suggest biopsy tests. Hence, sensitivity is considered to be an
important property of a biosensor.
Linearity
Linearity is the attribute that shows the accuracy of the measured response (for a set of
measurements with different concentrations of analyte) to a straight line, mathematically
represented as y = mc, where c is the concentration of the analyte, y is the output signal,represented as y = mc, where c is the concentration of the analyte, y is the output signal,
andm is the sensitivity of the biosensor. Linearity of the biosensor can be associated
with the resolution of the biosensor and range of analyte concentrations under test. The
resolution of the biosensor is defined as the smallest change in the concentration of an
analyte that is required to bring a change in the response of the biosensor. Depending on the
application, a good resolution is required as most biosensor applications require
not only analyte detection but also measurement of concentrations of analyte over a wide
working range. Another term associated with linearity is linear range, which is defined as the
range of analyte concentrations for which the biosensor response changes linearly with the
concentration.
8. Applications of biosensors
Biosensors have a very wide range of applications that aim to improve the quality of life.
This range covers their use for environmental monitoring, disease detection, food safety,
defence, drug discovery and many more. One of the main applications of biosensors is the
detection of biomolecules that are either indicators of a disease or targets of a drug.
For example, electrochemical biosensing techniques can be used as clinical tools to detect
protein cancer biomarkers. Biosensors can also be used as platforms for monitoring food
traceability, quality, safety and nutritional value. These applications fall into the category
of ‘single shot’ analysis tools, i.e. where cost-effective and disposable sensing platforms
are required for the application. On the other hand, an application such as pollution
monitoring requires a biosensor to function from a few hours to several days. Such
biosensors can be termed ‘long-term monitoring’ analysis tools. Whether it is long-termbiosensors can be termed ‘long-term monitoring’ analysis tools. Whether it is long-term
monitoring or single shot analysis, biosensors find their use as technologically advanced
devices both in resource-limited settings and sophisticated medical set-ups: e.g. with
applications in drug discovery; for the detection of a number of chemical and biological
agents that are considered to be toxic materials of defence interest for use in artificial
implantable devices such as pacemakers and other prosthetic devices and sewage
epidemiology.Arange of electrochemical, optical and acoustic sensing techniques have
been utilised, along with their integration into analytical devices for various applications.
