摘要： A method of manufacturing a retinal graft. The method includes: (a) preparing a scaffold material solution; (b) air-drying the scaffold material solution, to form a thin scaffold layer; (c) crosslinking the thin scaffold layer; (d) rehydrating the scaffold layer; and (e) applying retinal pigment epithelium cells onto the scaffold layer.

摘要： Methods and systems for Laser-Induced Forward Transfer are disclosed in which a microfluidic chip is used as the printing head. The head comprises a transparent upper region, a middle region comprising an intermediate layer channel and an ink channel in fluid connection with said intermediate layer channel, and a lower layer with an orifice in fluid contact with the ink channel. When material in the intermediate layer channel is irradiated by an energy source (typically a pulsed laser) at a spot opposite the orifice, the material is partially evaporated, creating a vapor bubble that creates a transient pressure increase when it collapses, thereby forcing ink out of the orifice and onto a receiving substrate.

摘要： A system for performing substrateless and/or local donor Laser Induced Forward Transfer (LIFT), comprising a reservoir comprising at least one opening and an energy source configured to deliver energy to a donor material within said reservoir, characterized by at least one of: said reservoir is embedded into a medical device; said reservoir is in fluid connection with a medical device; said reservoir is incorporated into a medical device; said reservoir contains at least one biologically active substance; and, said reservoir is in fluid connection with at least one source of at least one biologically active substance. This system enables deposition of material by LIFT without any need for a donor substrate. Methods of substrateless and local donor LIFT, in particular for medical and biological applications, are also disclosed.
