Nanopores in Biocompatible Polymer
Creatv has developed a fabrication process to make high-porosity polymer nanofilters with smooth, uniform straight nanopores and high-aspect-ratio. This method can produce a new generation of high-precision, high-porosity, biocompatible filters with predetermined pore sizes.
