Optical biosensors use light waves as a probe to detect molecules, and are essential for precise medical diagnostics, ...

Engineers at the University of California San Diego have achieved a long-sought milestone in photonics: creating tiny optical ...

Imagine detecting a single trillionth of a gram of a molecule—like an amino acid—using just electricity and a chip smaller ...

Abstract: This study investigates the double role of N-doped carbon quantum dots (N-CQDs) in dye-sensitized solar cells (DSSCs) that operate under diffused- and low-light intensity conditions. We ...
