Surface Engineering of Neural Implants

Abstract

Neural implants are a convergence of biomedical engineering, neuroscience, and technology that have the potential to greatly impact the treatment of neurological illnesses and improve human capabilities. The surface engineering of neural implants is a critical field that concentrates on altering the surfaces of implants to enhance their biocompatibility, functionality, and integration with brain tissues. This chapter explores different surface engineering processes, such as coating and layer deposition methods, including chemical vapour deposition (CVD) and physical vapour deposition (PVD). The paper also discusses texturing and patterning techniques, including laser texturing and photolithography. Biological functionalization approaches, such as immobilising bioactive compounds and grafting peptides, are being studied to improve the interaction between implants and brain cells. The text discusses the importance of materials in the construction of lasting and successful implants, with a focus on metals, polymers, and ceramics such as titanium, polyimide, and silicon carbide. The examination focuses on challenges pertaining to the durability and reliability of implants, the ability to scale surface treatments, and the intricacies of production processes. This chapter also emphasises the significance of strong approval processes and the ethical implications of implementing advanced neurological technology while addressing regulatory and ethical problems.
