Abstract

The design and development of micro patterns with enhanced surface area is crucial for improving the performance of biosensors. This study focuses on utilizing the laser engraving method to increase the surface area of micro patterns, thereby enhancing the sensitivity and selectivity of biosensors. Laser engraving provides precise control over the micro pattern geometry, allowing for the creation of intricate structures that promote efficient biomolecule immobilization. By optimizing the laser parameters, such as fluence, pulse duration, and scanning speed, high-resolution micro patterns can be achieved, resulting in increased surface roughness and maximized surface area. The fabricated laser-engraved micro patterns offer improved binding capacity and faster mass transport, enabling enhanced biosensor performance. This research aims to explore the potential of laser engraving as a method for improving the surface area of micro patterns in biosensors and advancing their analytical capabilities.
