Abstract
A system for biomolecular separation and detection of a molecular species includes a solid state laser detector having a sample channel therein. The presence of a molecular species is indicated by a frequency shift in the laser's output, which is detected by optical heterodyning the laser's output with the output of a reference laser. The interior of the sample channel is optionally coated with a ligand for binding the molecular species of interest. The system involves preprocessing a sample by electroosmotic separation in channels that are lithographically formed in a two-dimensional planar substrate. Molecular separation is also accomplished in a nanostructural molecular sieve comprising spaced apart posts defining narrow channels therebetween.
