Nanotechnology applications in breast implant manufacturing for improved durability and functionality

Abstract

Breast implants are often used in restorative and cosmetic surgeries. However, the materials used for implants today could be better regarding biocompatibility and mechanical strength. It is possible to make composite biomaterials out of nanomaterials with better mechanical qualities than common implant materials like silicone elastomers and saline-filled shells. Researchers have found that adding carbon nanotubes, graphene, and hydroxyapatite nanoparticles to the shells of metal and silicone implants makes them much stronger, more flexible, and less likely to break. Researchers are also looking into polymer nanocomposites made of polycaprolactone and polylactic acid to see if they can break down better and integrate better with tissues. Changing the surface of implants at the nanoscale level can make them more biocompatible by controlling how proteins stick to the material and how cells interact with it. Animal tests with nanocoatings of polyacrylate, chitosan, and hyaluronic acid showed that they lowered the formation of capsules and inflammation. Antimicrobial nanoparticles, such as silver, zinc oxide, and antibiotics, are attached to the surfaces of implants to protect against infections and release drugs locally. Nanocontrast agents are used in high-resolution MRI and ultrasound images of implant shell integrity to get new imaging and diagnosis tools. By tracking biomarkers, nanostructured sensors could be used to find seromas, ruptures, and device failures with little to no damage. Much work has been done to show that different nanotechnologies can help breast implants in a pre-clinical setting. However, problems with regulation and standardization still need to be fixed before the implants can be used in people and made in large quantities. The process needs to be improved even more to make a lot of nanocomposite and etched surfaces. To make sure patients are safe, it is also important to do long-term biocompatibility and nanotoxicology tests. Nanotechnology has a lot of promise to change the way breast implants are made so that they look better and improve people's quality of life. This review examines nanotechnology's emerging applications for enhancing breast implants' durability and performance.
