today’s cyclodextrin:
CD-based microneedle patches for the delivery of water-insoluble drugs:
A patch incorporates biodegradable microneedles that are fabricated from naturally derived polymer conjugates of gelatin methacryloyl and β-cyclodextrin. When curcumin, an unstable and water-insoluble anticancer therapeutic agent, is loaded as an example, its stability and solubility are improved due to the formation of inclusion complex.
