Gold is a noble metal, and it is commonly used because of its resistance to oxidation and electrical, magnetic, and physical properties. Forming gold into nanoparticles allows researchers to use gold in areas that are too small for bulk gold to reach and brings with it new capabilities. Gold nanoparticles have been utilized for centuries by artists due to the vibrant colors produced by their interaction with visible light. Gold nanoparticles, exhibit good chemical stability, and they can be surface functionalized with almost every type of electron-donating molecule including biomolecules. Gold nanoparticles are undoubtedly very versatile. Gold nanoparticles have played an important and severe role in medicine since ancient times. Also, gold nanoparticle is the most suitable for drug delivery applications. Drug delivery using gold nanoparticles, in combination with their intrinsic capability for photothermal therapy, should be explored in the future.

 The development of genome editing tools, particularly those based on the CRISPR-Cas systems, is accelerating biological research and making it possible to conduct thorough genetic investigations in virtually any organism and cell type. Animal and stem cell-derived in vitro models of new model systems for studying the complexity of the nervous system has been made possible by these tools. Using CRISPR-Cas techniques, precise and effective gene editing can advance both fundamental and translational neuroscience research.
