Carbon microneedles
Why is it in news?
- Researchers from Indian Institute of Technology (IIT) Kharagpur developed tiny needles less than 1 mm in size.
- When arranged on a patch, the tiny hollow microneedles can be used for painless drug delivery.
Carbon microneedles
- Stronger and biocompatible needles:
- These gassy carbon needles were almost 300 times stronger than the original ones.
- Since it was made of carbon it was also biocompatible.
- No toxicity: these needles also showed any toxicity during testings.
- Controlled drug delivery: with these needles it can be possible to provide controlled drug delivery by managing the pressure.
- Painless administration of drugs: these needles are only 400 micrometer long, thus, it will be completely painless.
- Reduction in cost:
- Scientists said, just like a band-aid we can fabricate a dia-aid that can be used by diabetic patients for painless insulin administration.
- Since it is not possible to bring down the cost of insulin, this patch can reduce the device cost by almost 50%.
