Generation of multifunctional encoded particles using a tetrapod microneedle injector

초록

Here we describe a tetrapod microneedle injector that produces multifunction encoded particles. The custom-built tetrapod-like needle injector consists of spatially oriented microneedles operated by micropump using programmed on and off sequences. For the purpose of this study to achieve various functions from one particle, each constituent contained in a multifunction encoded particle confirms the cesium adsorption of PB, the drug release behavior of DTPA, and rapid mixing of immiscible liquids due to magnetic actuation. We believe that the multi-functionalized particles may have synergistic multifunctional properties and push the boundaries of advanced biomaterials in biomedical engineering.
