👉 Needle engineering is an advanced field of nanotechnology that focuses on the design, fabrication, and application of ultra-fine needles at the nanoscale to manipulate and interact with materials at an atomic or molecular level. These engineered needles can penetrate surfaces with minimal damage, enabling precise deposition, removal, or modification of materials without causing significant mechanical stress or contamination. This technology is pivotal in various applications, including drug delivery systems, where it allows for targeted and controlled release of therapeutic agents, as well as in materials science for creating nanostructured surfaces with tailored properties. Needle engineering leverages principles from physics, chemistry, and materials science to develop needles with specific geometries, coatings, and functionalities, enhancing their performance in diverse industrial and biomedical contexts.
