A method to create smart and flexible switches for the regulation of liquid flow across multiple channels is essential in paper microfluidics. Prior approaches are hampered by long response times, high actuation fluid volumes, and external control circuitry. To diminish these problems, we designed a distinctive actuator device fashioned entirely from chromatography paper and featuring folds. The fold can be selectively wetted by an actuation fluid at either the crest or trough, resulting in the raising or lowering of the actuator's tip and thus bringing about the connection or severance of fluidic channels. This actuation principle reduces the response time to only two seconds and the amount of fluid used to merely four microliters. We have also added six switch arrangements which can be divided into single-pole single-throw (normally OFF and normally ON) and single-pole double-throw (with single and double break). The utilization of six actuators in a parallel system allowed us to construct an autonomous colorimetric assay for the detection of three analytes - glucose, protein, and nitrite - in artificial saliva. This study has brought the concept of origami to paper microfluidics, allowing the use of multiple-fold geometries for the programmable switching of fluidic connections.

The transmembrane proteins known as ion channels play a role in controlling and preserving the ionic concentrations across the cell membrane. Modeling the flux of ions in and out of these channels on an atomic level is essential for understanding several neurological diseases and related pharmaceutical discoveries. Recent experimental research has provided information on the channel's physical structure which can be used to create realistic ion transport models. Different trajectories exist for the ions entering the channel, each having its own probability of occurrence. Variables that measure these trajectories are the translocation and return probabilities, average lifetime, and spectral density of the ion number fluctuations. Theoretical analysis of ion transport has been restricted to low-resolution continuum diffusion-based or kinetic-based models which do not consider important factors that have an effect on ionic conduction. This paper extends previous models by an electro-diffusion model which takes into account the effects of electric fields, energy barriers, and rate-limited association/dissociation of ions with surface charges present inside the channel. Derived from the analytical model are the survival probability and spectral density. :Analytical Modeling of the Ion Number Fluctuations in Biological Ion Channels" Journal of Nanoscience and Nanotechnology; Vol. 12, 2489–2495, 2012

This paper presents a remote monitoring tool for the objective measurement of behavioral indicators that can help in assessing the health and welfare of pigs in precision swine production. The multiparameter electronic sensor board can measure posture, gait, vocalization, and external temperature, and has been characterized through laboratory measurements and animal tests. Machine learning algorithms and decision support tools can be implemented to detect animal lameness, lethargy, pain, injury, and distress. The adoption of this technology could lead to more efficient management of farm animals, better targeting of sick animals, lower medical costs, and fewer antibiotics being used. Challenges and a road map for technology adoption are discussed, along with suggestions for future improvements. Animals 2021, 11(9), 2665; https://doi.org/10.3390/ani11092665

In this study, two sets of experiments were conducted in order to investigate the impact of static magnetic fields on the growth and ethanol production of Saccharomyces cerevisiae. The first experiment ran for 25 hours with a 2% dextrose loading rate, while the second ran for 30 hours with a 6% dextrose loading rate. The magnetic fields used were homogeneous and non-homogeneous, with strengths of 100 mT and 200 mT, respectively. The results showed that the homogenous magnetic field had no significant effect on cell growth, whilst the non-homogeneous field yielded an increase of approximately 8% in peak ethanol concentration compared to the control.

Magnetic Field to enhance ethanol production

Iowa State University

Two experiments were conducted to analyze the influence that magnetic fields have on cell growth and ethanol production during fermentation. The first experiment was conducted for 25 hours at a 2% dextrose loading rate with a homogeneous and non-homogeneous static magnetic field of 100 mT and 200 mT, respectively. The second experiment was conducted for 30 hours at a 6% dextrose loading rate with a non-homogeneous static magnetic field of 200 mT. The results indicated that homogeneous magnetic fields did not have a significant effect on the yeast cell growth. However, the non-homogeneous static magnetic field resulted in about 8% more peak ethanol concentration than the control for the 2% dextrose loading rate.

To evaluate the severity of SCN infections in the field, population densities of nematode eggs must be calculated. A method utilizing OptiPrep as a density gradient medium has been shown to provide more effective separation and recovery of extracted eggs compared to sucrose centrifugation. Furthermore, computerized processes have been established to facilitate the discernment and enumeration of eggs from processed samples. A high-resolution scanner was employed to capture static images of eggs and debris on filter papers, and a deep learning network was trained to distinguish and count the eggs from the debris. Additionally, a lensless imaging setup was established using standard components, and the egg samples were allowed to pass through a microfluidic flow chip created from double-sided adhesive tape. Holographic videos were then recorded of the eggs and debris as they moved through, which were reconstructed and processed by a custom software program to obtain the egg counts. The software programs' efficacy for egg counting was validated using soil samples obtained from two farms, and the results were compared to those obtained through manual counting.

Parasite Nematode Egg Extraction and Counting

To evaluate the level of infestation of the soybean cyst nematode (SCN), Heterodera glycines, in the field, egg population densities are determined from soil samples. Sucrose centrifugation is a common technique for separating debris from the extracted SCN eggs. We have developed a procedure, however, that employs OptiPrep as a density gradient medium, with improved extraction and recovery of the eggs compared to the sucrose centrifugation technique. Also, we have built computerized methods to automate the identification and counting of the nematode eggs from the processed samples. One approach uses a high-resolution scanner to capture static images of the eggs and debris on filter papers and a deep learning network is trained to detect and count the eggs. The second approach utilizes a lensless imaging setup with off-the-shelf components and the egg samples flow through a microfluidic flowchip. Holographic videos are taken of the passing eggs and debris, which are then reconstructed and processed by a custom software program to calculate egg counts. To evaluate the performance of the software programs, SCN-infested soils were collected from two farms and the results were compared with manual counts.

This study uses the model organism, C. elegans, to investigate its sensitivity and response to static magnetic fields. Wild-type C. elegans are put into microfluidic channels and exposed to permanent magnets for five cycles of thirty-second time intervals at field strengths ranging from 5 milli Tesla to 120 milli Tesla. Recorded and analyzed with custom software, the results of the worm's movement - the average velocity, turning and curling percentage - were compared to control experiments. Surprisingly, the results did not show any significant difference, indicating that C. elegans may not be able to sense static magnetic fields at the range of field strengths tested.

This paper explores how the adaptability of Caenorhabditis elegans locomotion behavior can be assessed through a movement-based assay. This assay is set up with a series of sinusoidal microchannels, featuring a fixed wavelength and modulating amplitude. These channels are comparable to the body diameter of the organism, and worms are allowed to travel from the input port to the output port. In regions that closely fit the worms' natural undulations, progress is quick and steady. As the channel amplitude changes along the device, the worm struggles to generate propulsive force, slows down, and eventually is unable to move forward. An array of locomotion parameters (average forward velocity, number and duration of pauses, range of contact angle, and cut-off region) are generated from the recorded videos to measure how the worm moves in the modulated sinusoidal channels. The device is tested on wild-type (N2) and two mutant (lev-8 and unc-38) C. elegans. We suggest that this passive, movement-based assay can be used to differentiate between nematodes with distinct locomotion phenotypes.

Automated sorting of parasitic worms using sine-wave channels

Every year, soybean yields are reduced by numerous diseases, especially the soybean cyst nematode (SCN). Identifying the presence of SCN and measuring its population densities in the field is challenging as there are no visible signs of disease. The only sure way to evaluate SCN population levels is to extract the cysts from the soil, extract the eggs from the cysts, and count them. Currently, this extraction process is typically done in commercial soil analysis laboratories and university plant diagnostic clinics and requires multiple steps. To make this process easier, we have created a robotic instrument that can automate the extraction of nematode cysts from soil and the subsequent release of their eggs. This technology is operated using a touchscreen interface and is tested using soil samples from two farms. The results are comparable to the conventional technique. Our robotic instrument makes SCN soil diagnostics more efficient, aiding in the long-term integrated pest management of this harmful soybean pest.

In this paper, we present a microfluidic method to observe and analyze the physical elements of nematode navigation in real-time. We use microfluidic devices consisting of T-maze or cylindrical structures with varying geometry to study how nematodes make decisions. We found that the angle of the T-maze intersections affects the decision-making of these microscopic, soil-dwelling worms. Additionally, we were able to passively guide nematodes in a linear direction by adjusting the position and spacing of cylindrical obstacles in their path. To test our method, we conducted experiments on two nematode species (C. elegans and Oesophagostomum dentatum) without the use of chemical or electrical stimulants.

We developed a micro-fluidic method to observe the physical aspects of nematode navigation in real-time. This method involves constructing a series of interconnected T-maze or cylindrical structures of varying geometry. Through this, we were able to demonstrate that the decision-making of nematodes is affected by the angle of the T-maze intersections and that they can be directed to move in a linear direction by adjusting the position and spacing of cylindrical obstacles. Our experiments were conducted on two nematodes (C. elegans and Oesophagostomum dentatum) and no chemical or electrical stimulants were employed.
