Abstract

One or more microbeams derived from a corresponding number of Vertical Cavity Surface Emitting Lasers (VCSELs) are used to manipulate and to transport inorganic and organic objects. The optical tweezing apparatus and method is compact size, and suitable to manipulate multiple objects in an array concurrently, and in parallel.
