Microscopic Swimming Nanorobot Penetrates Body Fluids And Assists In Drug Delivery

Nanorobots can be programed to wipe out cancer cells and deliver medicine specifically to parts of the body affected by disease.

Scientists, in cooperation between the Swiss Federal Institute of Technology in Zurich and Israel Institute of Technology (Technion) have developed microscopic nanoswimmers or nanorobots that can penetrate blood and even thicker liquids that existwithin the body.

Nanorobots could become standard practice to deliver medicine specifically to parts of the body affected by disease. They could be programmed to specifically wipe out cancer cells, which would lower the risk of complications, reduce the need for invasive surgery and lead to faster recoveries.

Drug Delivery System
Drug delivery systems, is a technology using various chemicals to bind the target drugs, carry them to target organ, tissue or cell where the drug is released at a pre-determined rate.

The researchers strung together three links in a chain about as long as a silk fiber is wide. One segment was a polymer, and two were magnetic, metallic nanowires.

When applied an oscillating magnetic field, the nanoswimmer moved in an S-like, undulatory motion at the speed of nearly one body length per second.

The magnetic field allows the system to control the direction in which the nanoswimmers are moving, so any on-board cargo such as drugs or some sort of nanoparticles can be precisely placed inside a tumor.

Drug Delivery Systems - Use in Diabetes Management
Different types of drug delivery systems for insulin delivery have been extensively researched recently. Oral route and transdermal drug delivery systems are among the advanced drug delivery systems.

Oncology Drug Delivery Systems
Drug delivery in oncology offers a localized, prolonged and protected drug interaction with the cancer cells and reduces the side effects.

Stimuli-Responsive Drug Delivery System Stops Transplant Rejection
Following a tissue graft transplant —such as that of the hand, face, arm or leg— it is standard for doctors to immediately give transplant recipients immunosuppressant drugs to prevent their body's immune system from attacking and rejecting the new body part.
