To develop the technology, the researchers built a sensor by embedding upconversion optical probes into three-dimensional ...

This sensor could detect digoxin levels as low ... Quenchbody (Q-body): A type of fluorescent immunosensor that utilizes a mechanism of photoinduced electron transfer to enhance detection sensitivity.

In this work, authors present a supramolecular fluorescent sensor array that enables the accurate discrimination of intracellular bacteria, also demonstrating that this can be modified as a host ...
