Using noninvasive or least invasive neuro stimulation (preventing the tissue damage) in topical and intensive lighting of the different parts of brain is a main challenge in optogenetics. By designing gold coated tapered tip optical fiber using chemical etching (important points about this method in fabrication of tapered tip fiber are: concentration of acid, temperature and pressure), it will be possible to send the light in a more localized manner to the target area. Surface Plasmon resonance can enhance potential reaction of neuron. It will be possible to stimulate different parts of brain by coupling laser light to the optical fiber.
