The preservative isn't infinitely effective
Chitosan, as a natural cationic polysaccharide, has excellent biocompatibility, biodegradability and low immunogenicity
A week past expiration with perfect storage history presents lower risk than medication that is months expired or poorly stored, but no clinical data supports using it
Oral, liposomal, or topical options may be preferred for many patients because they are gradual and easier to maintain, while IV glutathione should be considered only after proper medical evaluation and under qualified supervision
Figure 1 2 Advantages of COF-based nanoplatforms for cancer therapy Unlike MOFs, COFs are typically constructed entirely from light elements linked by strong covalent bonds, rendering them inherently metal-free and generally free from the risk of toxic metal ion leaching, which contributes to their favorable biocompatibility (159, 160)
