Rest assured, we've "seen" methods of delivering injections sans pain, but we've yet to actually experience this phenomenon ourselves. If Dr. Roger Narayan has anything to do about it, however, we may not feel even a pinch the next time the blood drive comes calling. A team of researchers led by the aforementioned individual has reportedly been able to use "two-photon polymerization of organically modified ceramic (Ormocer) hybrid materials to create microneedles resistant to breakage," and they can also be made in a wider range of sizes than metal counterparts. It's said that these very needles would be "so fine that patients wouldn't feel them piercing their skin," and while that sure sounds delightful, we've no idea how many more visits we'll make before finding one of these in the nurse's hand.
