Abstract: The present disclosure provides systems, devices, and methods for penetrating a biological membrane. The system may comprise a laser unit configured to generate one or more laser beams. The system may comprise a set of targeting optics configured to direct the one or more laser beams to a target region of the biological membrane. The system may comprise a raster scanner operatively coupled to the laser unit and the set of targeting optics. The system may comprise a non-transitory computer readable storage medium comprising a set of instructions. The set of instructions may be configured to control at least one of the laser unit, the set of targeting optics, or the raster scanner to photodisrupt the target region of the biological membrane to a target depth while minimizing damage to one or more blood vessels in proximity to the target region.

Abstract: Disclosed herein is a tissue harvester comprising a substrate having an airfoil shape; and a textured surface disposed upon the substrate, where the textured surface comprises a spatial array of nanometer or micrometer sized pillars of varying cross-sections. Disclosed herein too is method comprising disposing upon a substrate a textured surface; where the substrate has an airfoil shape and where the textured surface where the textured surface comprises nanometer or micrometer sized pillars; contacting the tissue harvester with biological cells whose proliferation under different conditions is desired; and disposing the tissue harvester in a flow field such that cells disposed on the tissue harvester at different locations may experience different flow fields.
