Claim Text:
1. A high-speed microfluidic switch, said switch comprising: a first microfluidic channel comprising a bifurcation into a first path and a second path; a liquid or gel filled second microfluidic channel adjacent to said first microfluidic channel where said liquid or gel flows through said second microfluidic channel and said second microfluidic channel is disposed such that formation of a gas or plasma cavitation bubble in the liquid or gel in said second microfluidic channel redirects particles flowing into said first path so they flow into said second path; a pulse laser focused on said second microfluidic channel and configured to provide sufficient energy to form said cavitation bubble; wherein said switch comprises a wall between said second channel and said first channel where said second microfluidic channel and said wall are disposed such that formation of a gas or plasma bubble in said second channel deforms said wall to redirect particles flowing into said first path so they flow into said second path.
