2020-195 - Contactless, Damage-Free, High-Precision Cell Extraction and Transfer through Acoustic Droplet Ejection

Market Opportunity Isolating cells is an important step before next-generation sequencing, Sanger sequencing, PCR, and proteomics. The current cell extraction techniques such as pipetting or laser capture microdissection (LCM) produce unwanted damage to the extracted cells and remaining cells. Moreover, while pipetting offers good precision, it is...

2020-194 - Pick and Placement of Semiconductor Chips Based On Nozzleless Self-Focusing Acoustic Droplet Ejector

Abstract USC researchers have invented an apparatus and affiliated process capable of on-demand picking and placing of semiconductor chips based on a nozzleless acoustic droplet ejector which ejects liquid droplets to carry very small semiconductor chips or dies to a targeted substrate. Currently, almost all commercially available liquid droplet ejectors...
