Abstract

Disclosed herein is a generalizable and intuitive strategy to photomodulate biomaterials in full 3D non-discrete patterns across cellular scales through grayscale image z-stack-guided multiphoton optical-lithography (GIZMO). In one aspect a method for optical patterning of a material is presented with the method comprising of initializing a laser, wherein the laser is focused through an objective that is movable in the x, y, and z directions; wherein a laser intensity is modulated while in motion or progress throughout a raster scanning.
