Furthermore, recent studies show alumina-based ceramics loaded with silver nanoparticles exhibit potent bactericidal effects through disrupting the bacterial membrane surface and altering the binding affinity between cell components such as nucleotides and monosaccharides leading to whole-cell degradation.
Ceramics in Drug Delivery
Drug delivery systems are pharmaceutical formulations responsible for holding and releasing drug molecules to target sites while preserving its efficacy. The ideal formulary should release drugs gradually in a predictable manner, precisely at the organ site of action without harming nearby healthy tissues. Ceramics in drug delivery play an active role in making these perfect conditions possible as they permit fine-tuning of drug release kinetics based on various external stimuli such as pH changes, applied magnetic fields, and temperature. This functional property arises from the inclusion of several porous channels within the ceramic structural input, which serves as interconnected pathways regulating transport behavior. These can be tuned by changing chemical composition and particle size distribution resulting in improved cellular response and optimal administration of anticancer agents.
