Hollow glass microspheres can be used as a drug delivery system due to their unique properties, such as high surface area to volume ratio, controllable size and shape, and ability to encapsulate drugs within their hollow cores.
When used as a drug delivery system, hollow glass microspheres can protect the drug from degradation and can control the release of the drug over an extended period of time. This controlled release can be achieved by adjusting the size and thickness of the microsphere wall, which affects the diffusion of the drug out of the microsphere.
Hollow glass microspheres can be made from a variety of materials such as polymers, ceramics, and metals, which allows for customization of the microsphere properties to match the specific drug delivery needs. In addition, surface modifications can be made to the microspheres to enhance their targeting ability, allowing for more specific drug delivery to certain cells or tissues.
