| Summary: | In situ microbial aerodynamic microneedles (MM-MNs) represent an autonomous transdermal drug delivery platform that utilizes the gas generated by microbial metabolism (e.g., H2, NO, and H2S) to propel drugs into deep tissues, surpassing the penetration limits of traditional microneedles reliant on external stimuli (heat/light/mechanical force). By leveraging controlled microbial metabolism, MM-MNs enable energy-independent, spatiotemporally precise delivery with enhanced targeting and bioavailability. Gas-driven propulsion combines with bioactive gas functions (e.g., NO-induced vasodilation and H2S-mediated anti-inflammation) to modulate disease microenvironments. The system’s biocompatibility (probiotic strains and Lactobacillus) and scalability (cost-effective patch design) further support its potential for localized therapies (skin diseases and tumors) with minimized systemic exposure. This innovation bridges microbial biotechnology and precision medicine, offering a paradigm shift in transdermal delivery. |
