This novel sensor detects acoustics from particles using the photoacoustic process, implying improved sensing efficiency in native environments.
We demonstrate an optofluidic microsensor that overcomes conventional evanescent field limitations by detecting acoustics from particles undergoing photoacoustic process. This label- free, real-time sensing approach extends sensing efficiency, enabling molecular and cellular analysis in native environments.
