These patches consist of micron-sized needles that painlessly penetrate the skin's outermost layer, enabling the controlled release of medications or therapeutic agents. ...
Microneedle Technology Microneedle technology offers a minimally invasive approach to drug delivery by creating microscale needles that can penetrate the skin. This technology has gained attention for its ability to enhance drug absorption and bypass certain physiological barriers. ...
Drugs are preloaded in the hollow structure of the needle body or in the needle cavity. After the hollow needle tip penetrates the skin, the drug enters the body under the pressure of the interstitial fluid concentration gradient to achieve drug delivery. ...
Approximately 20 percent of microbes reside in the dermis layer, and when a needle penetrates the skin, some of these microbes are collected by the needle and can enter the blood culture bottle. ...
The researchers investigated the fundamental interactions between graphene-based films and the mosquito species Aedes aegypti through a combination of live mosquito experiments, needle penetration force measurements, and mathematical modeling of mechanical puncture phenomena. ...
