150 . An implantable light conduit comprising:
a distal end comprising a surface configured to be implanted in a subject,
a proximal end; and
an elongate body extending between the distal end and the proximal end,
wherein the surface of the implantable light conduit comprises one or more reagents configured to be delivered to the subject.
151 . The implantable light conduit of claim 150 , wherein the light conduit comprises one or more members selected from the group consisting of a lens, an optical fiber, and a glass window.
152 . The implantable light conduit of claim 151 , wherein the light conduit comprises a lens, wherein said lens comprises a gradient-index (GRIN) lens.
153 . The implantable light conduit of claim 150 , wherein the light conduit comprises a volume equal to or less than 10 cm 3 .
154 . The implantable light conduit of claim 150 , wherein the light conduit comprises an electrode.
155 . The implantable light conduit of claim 150 , wherein the surface comprises pores to which the one or more reagents adhere to.
156 . The implantable light conduit of claim 150 , wherein the one or more reagents comprise drugs, viruses, cells, or other biological materials.
157 . The implantable light conduit of claim 156 , wherein the one or more reagents comprise adeno-associated viruses (AAV).
