We demonstrate the optical manipulation of nanoliter aqueous droplets containing surfactant or lipid molecules and immersed in an organic liquid using near-infrared light. The resulting emulsion droplets are manipulated using both the thermocapillary

Lipid bilayers are formed when pairs of lipid-coated aqueous droplets in a mineral oil matrix are brought into contact via laser-induced thermal motion of the matrix. We characterize these bilayers for biomimetic platforms.

We apply optical microfluidic methods to cell studies including: nanoliter polymerase chain reaction amplification of DNA/RNA, useful for circulating tumor cells; and preparing artificial bilayers, useful for transmembrane protein function.

Circulating tumor cells can provide important diagnostic information using blood samples instead of direct biopsy of a solid tumor. We report development of an optical microfluidics method for molecular analysis of circulating tumor cells.

We report the successful application of low-power (approximately 30 mW) laser radiation as an optical heating source for high-speed real-time polymerase chain reaction (PCR) amplification of DNA in nanoliter droplets dispersed in an oil phase. Light

Infrared transillumination is used to detect cancerous tissue in a human xenograft mouse model. Vasoactive agents are used to provide exogenous contrast by altering response from blood chromophores hemoglobin and oxyhemoglobin.
