Abstract
The invention discloses a polymer micro-needle array chip, comprising a substrate and a micro-needle array standing thereon; the material for preparing the micro-needle array is a polyacrylamides polymer, with the molecular weight of 1.0×104-2.0×105, the Vickers hardness of 150-600 HV, and the impact strength of 5-30 J/m. The polymer micro-needle array chip has a high mechanical strength and a sharp needle tip, and it can easily dissolve or swell on contact with a water-containing environment, which helps the drug to be released slowly in the skin.
