Building on previous work, researchers at Duke University have developed a new technology that wraps nanoshells in a thin film of drug-infused hydrogel, adding additional firepower to the already promising targeted cancer treatment. The hydrogel is loaded with cancer-fighting drugs and coated onto the nanoshells, which heat up when exposed to infrared light and release the chemotherapeutic drugs, delivering a one-two punch, directly to the tumour.
Nanorobots hold great potential in the field of medicine. This is
largely due to the possibility of highly-targeted delivery of medical
payloads, an outcome that could lessen side effects and negate the need
for invasive procedures. But how these microscopic particles can best
navigate the body's fluids is a huge area of focus for scientists.
Researchers are now reporting a new technique whereby nanorobots are
made to swim swiftly through the fluids like blood to reach their
Scientists are increasingly looking at using medication-filled microspheres for targeted drug delivery within the human body. Silicone would
be a particularly good building material for such spheres, as it's
biocompatible, waterproof, and chemically stable. Unfortunately, using
traditional methods, it can't be made into small enough spheres. Now,
however, a new process has allowed for the creation of silicone
microspheres that are about one one-hundredth the size of any previously
