Biosensors for Bacterial Detection
Bacteria are present widely in various environments, such as soils, marine and estuarine water, intestinal tract of animals, and waste water. Normally, the bacteria are not visible to human eyes due to their small size of usually a few micrometers in length, with the shapes of spheres, rods or spirals. The presence of bacteria can be harmful to human/animal health, food safety, environmental co...
متن کاملBiosensors for whole-cell bacterial detection.
Bacterial pathogens are important targets for detection and identification in medicine, food safety, public health, and security. Bacterial infection is a common cause of morbidity and mortality worldwide. In spite of the availability of antibiotics, these infections are often misdiagnosed or there is an unacceptable delay in diagnosis. Current methods of bacterial detection rely upon laborator...
متن کاملLarge Scale Bacterial Colony Screening of Diversified FRET Biosensors
Biosensors based on Förster Resonance Energy Transfer (FRET) between fluorescent protein mutants have started to revolutionize physiology and biochemistry. However, many types of FRET biosensors show relatively small FRET changes, making measurements with these probes challenging when used under sub-optimal experimental conditions. Thus, a major effort in the field currently lies in designing n...
متن کاملBacterial Biosensors for Measuring Availability of Environmental Pollutants
Traditionally, pollution risk assessment is based on the measurement of a pollutant's total concentration in a sample. The toxicity of a given pollutant in the environment, however, is tightly linked to its bioavailability, which may differ significantly from the total amount. Physico-chemical and biological parameters strongly influence pollutant fate in terms of leaching, sequestration and bi...
متن کاملNatural Bacterial Communities Serve as Quantitative Geochemical Biosensors
UNLABELLED Biological sensors can be engineered to measure a wide range of environmental conditions. Here we show that statistical analysis of DNA from natural microbial communities can be used to accurately identify environmental contaminants, including uranium and nitrate at a nuclear waste site. In addition to contamination, sequence data from the 16S rRNA gene alone can quantitatively predi...
