Nanotechnology in Nanofabrication: Techniques and Challenges

Abstract

Nanofabrication, the cornerstone of nanotechnology, enables the manipulation and assembly of materials at the nanoscale for applications ranging from electronics to biomedicine. This article presents a comprehensive overview of the techniques used in nanofabrication, including top-down and bottom-up approaches, along with advanced lithographic and self-assembly methods. While significant progress has been made in precision engineering and scalability, several challenges remain, such as cost-effectiveness, reproducibility, and integration with conventional manufacturing. This study outlines critical techniques, highlights technological barriers, and suggests future directions for scalable, reliable nanomanufacturing.
