    摘要: 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.

    摘要: The present invention provides a method of forming one or more biological-binding areas on a substrate for biological-testing. The method includes activating at least a portion of a glass-ceramic substrate comprising glass and one or more metal containing compounds. The one or more metal containing compounds have a range of diameters that are less than about 300 nanometers in diameter and are spaced an average distance of at least one-half the midpoint of the diameter range apart. The one or more metals include compounds selected from metal oxides, metal nanoparticles, metal alloys, and atomic metals. The glass-ceramic substrate is heated to a temperature near the glass transformation temperature to form one or more metal nanoparticles in one or more ceramic biological-binding areas. The glass-ceramic substrate is etched to expose one or more metal. One or more biological molecules are contacted with one or more ceramic biological-binding areas to provide one or more biological testing areas with an increased binding area as compared to un-activated areas.
