Abstract
Recently demonstrated microfluidic “chips” have the potential to be useful bioanalytical tools for DNA, protein, and cellular studies.1 To realize this potential, means for introducing fluids, separating their components, and detection must be integrated onto the chip. We have investigated semiconductor laser micro-cavity spectroscopy as a means for ultrasensitive detection of various fluids, cells, and particulates.2
