Microrobots Revolutionize Targeted Drug Delivery in Cancer Treatment
A Caltech-led team has developed bioresorbable acoustic microrobots (BAM) capable of targeted drug delivery within the body. These microrobots, made from a hydrogel, can navigate complex biofluids and release drugs precisely at tumor sites, as demonstrated in mice with bladder tumors. The microrobots incorporate magnetic nanoparticles for navigation and ultrasound imaging for real-time tracking. This innovation could revolutionize precision medicine by delivering therapeutic agents directly to specific sites, minimizing side effects and improving treatment efficacy.
