Skin patch could replace the syringe for disease diagnosis
from Medical News Today
Drawing blood and testing it is standard practice for many medical diagnostics. As a less painful alternative, scientists are developing skin patches that could one day replace the syringe. In the ACS journal Analytical Chemistry, one team reports they have designed and successfully tested, for the first time, a small skin patch that detected malaria proteins in live mice. It could someday be adapted for use in humans to diagnose other diseases, too. Researchers note that while blood is rich with molecular clues that tell a story about a person's health, withdrawing it is often painful. It also requires trained personnel and expensive lab equipment and facilities for analysis.
