Disposable article that include fibers formed from compositions comprising thermoplastic polymers and waxes are disclosed, where the wax is dispersed throughout the thermoplastic polymer.

Provided is an aqueous liquid composition including a water-based medium containing water, a polymer having at least one type of groups selected from hydroxyl groups and amino groups, and phosphonobutanetricarboxylic acid. The polymer is at least one polymer selected from the group consisting of a polysaccharide, polyamino acid, polyvinyl alcohol, polyallylamine, polyvinylamine, a polyamidine, a polyethylenimine, and their derivatives.

The invention provides a non-particulate cross-linked poly--lysine polymer. The poly--lysine and cross linker are linked by amide bonds and may the cross linker has at least two functional groups capable of reacting with an alpha carbon amine of poly--lysine. The polymer is suitably insoluble in water and other solvents and is provided in macro form for example a sheet, article or fiber. The macro form polymer is useful in a wide range of applications including wound treatment, as a medical diagnostic comprising a particulate support and a functional material bound or retained by the support and solid phase synthesis of peptides, oligonucleotides, oligosaccharides, immobilization of species, cell culturing and in chromatographic separation.

The present disclosure relates to coated substrates, capillaries and microfluidic channels which exhibit an extended shelf life compared to uncoated substrates. More specifically the disclosure relates to charged coatings at physiological pH which may prolong the shelf life of the substrate, capillary or microfluidic channel before being applied to biological fluids. Said shelf life is measured by the ability to provide a low fluid contact angle after an extended storage interval in ambient atmospheric conditions.
