drug delivery systems

RNA-DNA complexes that were modified with cholesterol made it into the brains of rats and mice, where they knocked down target genes.

Researchers are engineering microbes to deliver therapeutics specifically to tumors, maximizing the treatments’ efficacy while minimizing side effects.

Autonomous, living microrobots that seek and destroy cancer are not as futuristic as one might imagine, thanks to a fusion of robotics and synthetic biology.

Researchers could one day use the method to deliver antibiotics to topical wounds infected by hard-to-treat masses of bacteria.

A device implanted into mice can modulate brain circuit activity over long periods of time.

A microneedle delivers liquid medicines through tiny, fang-like points.

Mice receiving the treatment produced their own monoclonal antibodies and survived infection with the life-threatening pathogen Pseudomonas aeruginosa.

The mini machines treated infection somewhat better than antibiotics plus the typical proton pump inhibitor medication. 

Scientists designed autonomous nanovesicles capable of following glucose concentration gradients, even through the blood brain barrier in rats.
