On February 10, 2026, a study on the application of ethyl silicone oil in the surface coating of medical implants attracted industry attention. Researchers have successfully developed a medical grade ethyl silicone oil coating with antibacterial and anticoagulant functions through surface modification technology, providing new guarantees for the long-term safety of medical devices such as artificial joints and heart stents.


Traditional medical device surface coatings often use materials such as polytetrafluoroethylene, but there are problems such as insufficient biocompatibility and easy detachment. Ethyl silicone oil, due to its unique molecular structure, can firmly bond with metal or polymer substrates through covalent bonds, forming a durable and stable coating. Experiments have shown that the modified ethyl silicone oil coating can significantly reduce bacterial adhesion rate (by 92%), while inhibiting platelet aggregation, reducing the risk of thrombosis to below 0.3%.


The low surface tension characteristics of ethyl silicone oil enable it to uniformly cover complex instrument surfaces, forming a nanoscale protective layer, "the research team said." This technology has been validated through animal experiments and is expected to be applied in high-precision medical fields such as nerve conduits and ophthalmic implants in the future


In addition, progress has been made in the application of ethyl silicone oil in drug delivery systems. Researchers have developed a controllable release microcapsule carrier using its temperature sensitivity, which triggers drug release through body temperature and provides a new approach for targeted therapy of tumors.


With the increasing demand for material safety in the medical industry, ethyl silicone oil is gradually expanding from the industrial sector to the high-end medical market due to its non-toxic, non allergenic, and customizable characteristics. It is predicted that the global market size of medical ethyl silicone oil will exceed 500 million US dollars by 2026, with a compound annual growth rate of 12%.
