V. B. Neculaes, K.R. Conway, A.L. Garner, E. R. Loghin, S. Yazdanfar, D.V. Dylov, B. M. Davis, C. Joo, "Optical Based Delivery of Exogenous Molecules to Cells," U.S. Patent No. 8,778,682 B2 (issued July 15, 2014). 

Unlike normal laser-based methods of delivering molecules to biological cells, which use high power densities to puncture holes in a single cell, this patent describes a novel laser-based method that delivers molecules to multiple cells simultaneously with lower power density.  This design could provide a higher throughput for optically guided molecular delivery with improved cell viability.
