Abstract: A jammer system includes a jammer unit, a valve coupled to the jammer unit, and a sensor coupled to the valve. The jammer unit includes a jammer media and a membrane including an inlet. The membrane is configured to surround the jammer media. The valve is configured to allow a fluid to pass through the inlet of the membrane. The sensor is configured to cause actuation of the valve to evacuate the fluid from an interior of the membrane. The evacuation of the fluid from the interior of the membrane results in stiffening of the jammer media within the membrane.

Abstract: Compositions and processes for qualitative or quantitative one-step, two-site, tag/anti-tag or competitive non-bibulous lateral flow (immunochromatographic) assays for analytes in body fluids including chemically modified proteins as blocking and/or dispersing agents in conjunction with additives eliminating non-specific interference with the detection agents and/or binding partner caused by endogenous polypeptide constituents. Composition of the chemically modified proteins can be albumins. Composition of the chemically modified albumins can have altered charge and/or molecular weight. Process for composition of the chemically modified proteins can be prepared by modification of the nucleophilic groups. The chemical modification of nucleophilic groups in albmins can be introduced by anhydrides, alkyl acetimidates, methylating and/or cross-linking agents. The additives eliminating non-specific interference can be chemically modified albumins, heterophilic blockers and chaotropic agents.
