1. A method for at least partially encapsulating a three-dimensional (3D) object, comprising
(a) providing a media chamber comprising a medium comprising (i) said 3D object comprising a photo-emitter, wherein said 3D object is a biological material, (ii) at least one polymeric precursor, and (iii) a photoinitiator; and
(b) directing at least one energy beam to said medium in said media chamber to induce photo-emission from said photo-emitter wherein said photo-emitter emits energy that triggers said photoinitiator to initiate formation of a polymer matrix from said at least one polymeric precursor, which polymer matrix at least partially encapsulates said 3D object.
