Global Optogenetics Market was valued at USD 25.5 Mn in 2020, and is expected to reach USD 58.8 Mn by 2027, expanding at a CAGR of 19.9% from 2021 – 2027. Optogenetics is the biological technique in neuroscience used for controlling the cells in the living tissue with the help of a light. Optogenetics is majorly used for monitor and control the activities of neurons in living tissue. Light-sensitive proteins are used as key reagents in the optogenetics. The neuronal control achieved by using optogenetic actuators such as halorhodopsin, channelrhodopsin, and archaerhodopsin. Optical recording of the neuronal activities made with optogenetic sensors for the neurotransmitter, membrane voltage, vesicular release, or calcium. Optogenetics is adopted in the ophthalmology, cardiology, behavioural science, neuroscience, and others. Increase in the adoption of optogenetics in the behavioural and neuroscience, technological advancements in optogenetics, growth in ultrafast laser tool technology are the key factors driving the growth of the market. Moreover, rise in the number of research laboratories adopting optogenetics technology around the globe and development in the genetic engineering research expected to propel the optogenetics market over the forecast period. However, a high cost of the technology, lack of awareness about the optogenetics, and the dearth of skilled professionals for optogenetic research might hamper the market over the forecast period.
