A method including receiving a specimen comprising a carrier, a first target species, and a first component and storing at least a portion of the carrier and the first target species in a storage media by self-driven filtering of the specimen in the storage media, wherein the storage media comprises porous superabsorbent polymer (PSAP) beads. The PSAP beads provide for fast and self-driven microfiltration of biofluid samples. The treatment effectively separates small analytical targets (e.g., glucose, catalase, and bacteriophage) and large undesired components (e.g., bacteria and blood cells) in the biofluids by capturing the former inside and excluding the latter outside the PSAP beads. The treatment can reduce sample volume, self-aliquot the liquid sample, avoid microbial contamination, separate plasma from blood cells, stabilize target species inside the beads, and enable long-term storage at room temperature.

An article Including a support matrix including a plurality of pores, a metal oxide and a clay, wherein the metal oxide and the clay are disposed on the support matrix or within the plurality of pores of the support matrix, and a method of removing a hydrocarbon fluid and microplastics from an aqueous fluid by immersing the article into the aqueous fluid.

Sorbent material sheets are attached to an inner surface of an article having an enclosed volume, such as a cadaver pouch, an ammunition storage container, or a film or video tape storage box. The sorbent material sheets adsorb vapors which are released by the contents of the enclosed volumes, while providing flexibility and without releasing particles which could contaminate the contents of the enclosed volume.
