Cyclodextrin-Modified Zeolites as Drug-Delivery Nanocontainers
Zeolites modified with aminoalkoxysilanes and cyclodextrin show different uptake and release properties depending on which silane is used Multifunctional nanocontainers for imaging, targeting, and drug release are a main research area in bio-nanomedicine. Jurriaan Huskens and colleagues, University of Twente, The Netherlands, have functionalized nanoporous zeolite L crystals with β-cyclodextrin (CD) to give multifunctional systems… Continue reading Cyclodextrin-Modified Zeolites as Drug-Delivery Nanocontainers
