A biosensor is a device for the detection of an analyte that combines a biological component with a physicochemical detector component.
When pathogens attack the body, the innate immune system goes to work protecting against the invading disease.
A new study Dec. 18 in Nature reports an AI-driven advance in biotechnology with implications for drug development, disease detection, and environmental monitoring.
Imagine if houseplants could alert one to unsafe water conditions. Scientists are making strides toward this innovative idea by successfully modifying a plant to change its color to beet red when it detects the presence of a prohibited and harmful pesticide.
The electrochemical sensor, made of a graphitic nano-onion/molybdenum disulfide nanosheet composite, detects human papillomavirus (HPV)-16 and HPV-18, with high specificity.
Engineers have created nanoscale tattoos, which are dots and wires that adhere to living cells, bringing investigators one step closer to monitoring the health of individual cells.
Now that the emergency phase of the COVID-19 pandemic has ended, scientists are looking at ways to surveil indoor environments in real time for viruses.
Biosensors-;sensors that can detect biological samples-;are powerful tools for understanding the function, composition, and structure of biochemical molecules.
Alfalfa, also known in Latin as Medicago sativa, is an agricultural crop that is part of the legume family. It is known as a protein-rich food source for dairy cattle that is easily digested and can lead to increased milk production.
McMaster University researchers have devised a quick and low-cost test for Salmonella contamination in chicken and other foods that is simpler to use than a home COVID test.
Experts from the University of Barcelona, the Institute for Advanced Chemistry of Catalonia (IQAC-CSIC), the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) and the Aragon Nanoscience and Materials Institute of Aragon (INMA) -;a joint institute of the CSIC and the University of Zaragoza-; have developed a new method to detect RNA viruses based on the triplex-forming probe technology.
A synthetic biosensor that mimics properties found in cell membranes and provides an electronic readout of activity could lead to a better understanding of cell biology, development of new drugs, and the creation of sensory organs on a chip capable of detecting chemicals, similar to how noses and tongues work.
Although it frequently necessitates a challenging laboratory procedure, the quantitative detection of specific antibodies in complex samples like blood can provide information on a variety of diseases.
Engineering researchers have developed a battery-free, pill-shaped ingestible biosensing system designed to provide continuous monitoring in the intestinal environment.
Principal researchers at the Brain Science Institute (BSI) of the Korea Institute of Science and Technology were said to have discovered substantially decreased activity of focal adhesion kinase (FAK) proteins that play a significant role in neurite motility and proper synapse formation in HD patients’ brain tissues.
A developing area studies how clusters of molecules gather inside of cells, similar to how oil droplets form and separate from the water in a vinaigrette.
As the BA.5 omicron variant continues to spread, health experts are increasingly preparing for a future in which such COVID-19 variants emerge, surge and recede similar to seasonal flu.
The prescription humans use to manage high blood pressure, discomfort, or memory loss may one day originate from modified bacteria, cultivated in a vat like a yogurt, offering more inexpensive, sustainable drug options than people now have.
The detection and quantification of cancer-associated molecular biomarkers in body fluids, or liquid biopsies, prove minimally invasive in early cancer diagnostics.
Detecting the activity of CRISPR gene editing tools in organisms with the naked eye and an ultraviolet flashlight is now possible using technology developed at the Department of Energy's Oak Ridge National Laboratory.
Researchers have manipulated beta-lactoglobulin, or β-lactoglobulin, by using an Australian-made innovative thin-film microfluidic device.
