Abstract:
1. A method for biopatterning a biological target, the method including: obtaining a radiation pattern to be applied to an area of the biological target, wherein the biological target includes a first group of photosensitive elements, and wherein the first group of photosensitive elements is responsive to a first activation wavelength; radiating a first light beam of a first shape into the area of the biological target, wherein the first light beam includes a first radiation dose including the first activation wavelength, and wherein the first radiation dose does not satisfy an activation threshold for activating the first group of photosensitive elements; radiating a second light beam of a second shape into the area of the biological target, wherein the second light beam includes a second radiation dose including the first activation wavelength, wherein the second radiation dose does not satisfy the activation threshold, and wherein a combination of the first dose and the second dose satisfies the activation threshold; and activating the first group of photosensitive elements located within an intersection of the first light beam and the second light beam in the area of the biological target responsive to satisfaction of the activation threshold, wherein the intersection of the first light beam and the second light beam has a contour that matches at least a portion of the radiation pattern.
