Amorphous forms of silica and silicates are generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for oral delivery up to 1,500 mg per day. So, **is silica used in medicine?** Absolutely. This article explores its established and emerging roles, from its inert function as a pharmaceutical excipient to its revolutionary potential in advanced drug delivery systems.

While silver has been used for medical purposes for thousands of years, modern research, particularly involving silver nanoparticles (AgNPs), has revealed specific anti-inflammatory effects, especially in topical applications for wounds and inflammation. However, the anti-inflammatory action is not universal across all forms of silver and depends heavily on factors like particle size, concentration, and context.

With over 2.2 billion people globally suffering from vision impairment, nanotechnology offers a revolutionary approach to treatment [1.6.2]. So, what are nano drops used for? These advanced formulations enhance drug delivery, especially in ophthalmology, to treat conditions like dry eye, glaucoma, and more [1.3.3, 1.6.2].

Hydroxyapatite makes up about 97% of tooth enamel and 70% of bone, making it the hardest substance in the human body. **What is nanoXIM?** It is a brand of synthetic, nano-sized hydroxyapatite designed to mimic this natural mineral for medical and dental applications.
