The new carbon nanotube sensor design resembles a molecular toolbox that can be used to quickly assemble sensors for a variety of purposes -- for instance for detecting bacteria and viruses. An ...

Anions have an essential role in many biological processes including osmosis, ATP formation and DNA recognition. 1 They are widely used in many industrial processes such as electroplating. In ...

Researchers have created a nanophotonic chip system using lasers and bacteria to observe fluorescence emitted from a single bacterial cell. The novel system paves the way for an efficient and portable ...

Biological and chemical sensors that can detect extremely small concentrations are possible with fluorescent polymers. Chemists at Los Alamos National Laboratory and the University of California have ...

WEST LAFAYETTE, Ind. - A new type of electronic sensor that might be used to quickly detect and classify bacteria for medical diagnostics and food safety has passed a key hurdle by distinguishing ...

Sensor formats have been developed for detecting the activity of proteolytic enzymes based on fluorescent conjugated polymer superquenching. These sensors employ a reactive peptide sequence within a ...

Each year, bacterial infections claim several million lives worldwide. That is why detecting harmful microorganisms is crucial – not only in the diagnosis of diseases but also, for example, in food ...

Researchers have devised a new early warning system for catheter blockages: a polymer disk, placed in a urine collection bag, that releases a fluorescent dye (ACS Sensors 2018, DOI: 10.1021/acssensors ...

Bacterial runoff is a serious threat to our waterways and oceans; pathogenic microbes are known to contaminate stormwater that moves through sewers, picking up more microbial life before eventually ...

Microplastics are tiny, plastic fragments — many too small to see — found in the air, soil and water. Measuring their abundance in nature can direct cleanup resources, but current detection methods ...

An interdisciplinary research team from Bochum, Duisburg and Zurich has developed a new approach to construct modular optical sensors which are capable of detecting viruses and bacteria. For this ...
