Researchers report successful results from a hand-held breast cancer screening device that can detect breast cancer biomarkers from a tiny sample of saliva. Their design uses common components, such ...

Nanoparticles were first developed approximately 35 years ago [1]. They were initially developed as carriers for vaccines and cancer chemotherapy agents. In the first part of the paper we focused on ...

Monomeric near-infrared (NIR) fluorescent proteins (FPs) are in high demand as protein tags and components of biosensors for deep-tissue imaging and multicolour microscopy. We report three bright and ...

Imec and Genalyte have developed and produced a set of disposable silicon photonics biosensor chips to be used in Genalyte diagnostic and molecular detection equipment. The chips combine imec’s ...

Optical fiber biosensors (OFBs) achieve ultra-low detection limits for biomarkers and toxins, yet face challenges in reproducibility and scalable manufacturing.

Researchers have used off-the-shelf components to create a sensor device that is not only cost-effective but can quickly detect 32 different pathogens and has sensitivities on par with the ...

Dr. Ho Sang Jung and his research team from the Advanced Bio and Healthcare Materials Research Division at the Korea Institute of Materials Science (KIMS) have developed an optical biosensor capable ...

The biosensor uses "capture probes" called aptamers, which are single strands of DNA that bind to virus proteins, flagging them. The team's big challenge was finding a way to get these aptamers to ...

Wearable biosensors typically consist of a recognition region that detects the target signal, a transducer that converts that signal into a measurable parameter, and an electronic processor that ...

(Nanowerk Spotlight) Ensuring the safety of drinking water, food supplies, and environmental samples depends on detecting bacterial contamination before it causes harm. Traditional microbiological ...
