Abstract: This disclosure provides methods of using an eco-friendly colloidal silver-based composition in preventing and reducing contamination caused by microorganisms in the plant tissue culture processes. The composition comprises colloidal silver, a copolymer, surfactant, a base, and water. The methods allow cultivating plants or explants in a plant tissue culture medium under non-aseptic conditions and thus obviate the need of the cumbersome and laborious procedures to sterilize the culture medium and the culture vessel in order to create aseptic conditions for plant or explant cultivation.

Abstract: This disclosure provides an eco-friendly colloidal silver-based composition with the ability to prevent and control infections caused by pathogenic microorganisms in superficial organs of plants. The composition comprises water, colloidal silver, methyl vinyl ether copolymer, African palm vegetable oil, polyoxyethylene octylphenyl ether, triethanolamine, sodium hydroxide, and sodium benzoate. Due to its characteristics and the non-systemic application, the disclosed composition is non-toxic to host plants and other multicellular organisms.

Abstract: The present invention relates in general to a medical device consisting of a blocker made of a mixture of natural products such as African palm oil and the triglycerides thereof and natural waxes as active and emulsifying components, polymer and silver nanoparticles, acting as a blocker for latex protein and other skin irritants.

Abstract: The invention relates to a method for preparing specimens from tissue samples for cytology microscopic examination, and includes inventive compositions and a device used in said method. The invention also includes a diagnostic kit comprising the inventive compositions and device.

Abstract: Disclosed is a multi-layered test strip device for receiving whole blood on which a test for a suspected analyte is performed. The test confirms the presence, absence, or the amount of analyte, if present. The multi-layered device comprises two outside support layers between which are, in descending order relative to the horizontal plane, a) a spreading screen having defined characteristics, b) a separating layer which removes red blood cells at least partially via a red blood cell binding agent, and c) a membrane reagent layer; wherein the screen and each layer is in close and contiguous contact with the layer which follows it, and wherein at least one of layers a), b), and c) is conditioned by a pre-treatment.The screen can have openings of from 10-200 microns. The blood cell binding agents are antibodies to red blood cells, chemical agents, or lectins. The separating layer has screen opening of preferably 20-200 microns.
