Latest Patents
One of Arnold's latest patents is focused on "Cast membrane structures for sample preparation." This invention describes a method for casting-in-place composite and/or non-filled structures that serve as sorptive or reactive media or for size-based separations. The technology allows for the inclusion of a large amount of adsorptive particles in a polymer while maintaining the membrane's three-dimensional structure. In one preferred embodiment, the composite structures consist of particles entrapped within a porous polymeric substrate, which are cast in-place into a housing such as a pipette tip. This design provides an effective platform for micromass handling. The appropriate selection of particle chemistry enables various separation or purification operations, including selective bind/elute chromatography operations, on sample mass loads of less than 1 microgram in volumes of a few microliters. The invention also encompasses the composite structures and sample preparation devices containing them. In another preferred embodiment, self-retaining, self-supporting structures are cast in situ in a suitable housing, acting as a semi-permeable barrier for size-based separations.
