Abstract
Methods are provided for making microfilters by subtractive techniques which remove a component or part of a filter material to form pores in the filter material and additive techniques which deposit a filter material onto a porous underlying substrate. All the methods employ a supercritical fluid or mixture which have very high solvency properties and low viscosity and COis the preferred supercritical fluid.
