Quantum dot-based affinity biosensors in microfluidic systems offer an alternative SARS-CoV-2 diagnostics platform
In a new study published in
Emergent Materials, researchers show how microfluidic systems integrated with quantum dot-based affinity biosensors can serve as a valuable platform to rapidly and accurately diagnose severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
What are quantum dots?
Quantum dots (QD) are nanoscale semiconductor crystals (size: 2-10 nm) with unique optical and electronic characteristics. Such nanomaterials are widely used in biosensing applications for biomedical and bioanalytical purposes. Unlike organic dyes and protein-based fluorophores, QDs have a wide absorption spectrum and narrow emission bands, which make them very suitable for cell imaging and biosensor applications. Specifically, QDs can be used to trace multiple biological targets simultaneously with simple instrumentations. Other properties of QDs that make them superior to organic dyes include higher quantum efficiency and molar absorption coefficient. Because of the semiconductor properties, QDs can also be used in electrochemical applications.
