Abstract: An inexpensive and rapid method for fabricating arrays of hollow microneedles uses a photoetchable glass. Furthermore, the glass hollow microneedle array can be used to form a negative mold for replicating microneedles in biocompatible polymers or metals. These microneedle arrays can be used to extract fluids from plants or animals. Glucose transport through these hollow microneedles arrays has been found to be orders of magnitude more rapid than natural diffusion.

Abstract: An amorphous powder useful as a precursor for the preparation of crystalline aluminosilicates is prepared by forming a sodium aluminum silicate water mixture whose composition falls within specified ranges for forming sodium zeolite A. By dehydrating the mixture with a water miscible solvent prior to aging and crystal formation, an amorphous powder is recovered for future use. Upon subsequent treatment the amorphous powder can be converted to crystalline aluminosilicates including type 3A, 4A, 5A, X and Y.
