nano-patch-and-vaccinationTechnical difficulties with blood transfusions in medical sciences were removed in 1853 by the invention of the hypodermic syringe, with its hollow pointed needle. Credit for the evolution of this universally useful appliance is usually given to Doctor Alexander Wood.

Now, It has been one hundred sixty years the invention of the needle and syringe. Its heavy usage is still demanding its time to evolve.

Biomedical engineer Mark Kendall demos the Nano patch, a one-centimeter-by-one-centimeter square vaccine that can be applied painlessly to the skin.

He shows how this tiny piece of silicon can overcome four major shortcomings of the modern needle and syringe, at a fraction of the cost.

So it is hopeful that ‘Fear’ of needle, which is a major issue in countless people, could be resolved soon.
