Yes. Microspheres are already widely used in a range of applications. They are biocompatible and can be found in medical devices and cosmetics. Microspheres are common in dentistry, orthopedics, urology and many other medical fields. The microspheres are integrated within the cohesive gel and their bonding to the gel remains intact even in the unlikely case of the implant rupturing. The microspheres will not change in size or shape under temperatures and pressures that humans can normally withstand. There is no concern with flying, recreational diving, mountain climbing, etc.
