- Microneedles or Microneedle Patches or Microarray Patches are micron-scaled medical devices used to administer vaccines, drugs and other therapeutic agents. While microneedles were initially explored for transdermal drug delivery applications their use has been extended for the intraocular, vaginal, transungual, cardiac, vascular, gastrointestinal and intracochlear delivery of drugs. Microneedles are constructed through various methods usually involving photolithographic processes or micromolding. These methods involve etching microscopic structure into resin or silicon in order to cast microneedles. Microneedles are made from a variety of material ranging from silicon, titanium, stainless steel, and polymers. Some microneedles are made of a drug to be delivered to the body but are shaped into a needle so they will penetrate the skin. The microneedles range in size, shape, and function but are all used as an alternative to other delivery methods like the conventional hypodermic needle or other injection apparatus.
Microneedles are usually applied through even single needle or small arrays. The arrays used are a collection of microneedles, ranging from only a few microneedles to several hundred, attached to an applicator, sometimes a patch or other solid stamping device. The arrays are applied to the skin of patients and are given time to allow for the effective administration of drugs. Microneedles are an easier method for physicians as they require less training to apply and because they are not as hazardous as other needles, making the administration of drugs to patients safer and less painful while also avoiding some of the drawbacks of using other forms of drug delivery, such as risk of infection, production of hazardous waste, or cost.
