Principles of the present disclosure are directed to novel methods and devices for efficient and targeted delivery of impermeable exogenous materials such as small molecules, proteins, antibodies, and genes into cells, both in vitro as well as in vivo, which is of great importance for drug, vaccine and gene delivery for various therapeutic applications. Specifically, the invention provides device and method for targeted nano-enhanced optical delivery of opsins for vision restoration in patients with retinal photodegeneration by conventional intravitreal/sub-retinal injection of gold nano-rods and opsin plasmids followed by scanned/spatially modulated laser beam matching the pathological areas determined by Fundoscopy, OCT or scanning ophthalmoscope. |
