Silk Route for Nano Medical Devices
- Fibre created from spider silk has now proves to be stronger than untreated spider silk.
- The new thread was shown to be three times stronger than the untreated spider silk.
- Untreated spider silk is already one of the strongest substances in nature.
- Nano scale pharmaceuticals show great promise in fields of applications for health care.
A new study by scientists in the United States that coated spider silk with carbon nanotubes had created a fibre that was super strong and could conduct electricity. This new thread that was created was shown to be three times stronger than the untreated spider silk. Untreated spider silk as it is commonly known is already one of the strongest substances in nature.
The first application is in nano scale medical devices.
The study was published in the journal Nature Communications, and was led by Eden Steven of the National High Magnetic Field Laboratory in Tallahassee, Florida. In tests, the prototype has been found to be used as heartbeat monitor and also as a piston. This is able to raise a relatively huge 35 milligrams by using an electrical current and humidity that helps to make the thread contract like a muscle.
The nano scale pharmaceuticals and medical devices show great promise in various fields of applications for health care. It is important as the nano scale materials are used as delivery mechanisms so as to allow cells to absorb therapeutics into the cell wall.
