A solid article for sustained delivery of volatile materials in an interior space that is subject to temperature fluctuations of at least 5? C. Such solid article comprises one or more non-aqueous volatile materials in a chemically cross-linked gel. The chemically cross-linked gel is formed by mixing one or more polyols or derivatives thereof with a cross-linking agent at a weight ratio of from 1:0.1 to 1:0.8, and the solid article is characterized by a thermal conductivity of from 0.16 W/mK to 0.2 W/mK.

According to one embodiment, a virus inactivation kit can comprise: a tube for accommodating a sample containing viruses; a chamber comprising an inner space for accommodating the tube; and at least one light emitting module arranged on one side of the chamber in order to emit light at the tube, wherein the tube can be attached to or detached from the chamber.

The present invention relates to the field of antimicrobial agents active against Enterococcus bacteria. In particular, the present invention relates to a polypeptide comprising a first and a second amino acid sequence, wherein the first amino acid sequence is a sequence selected from SEQ ID NO:2; SEQ ID NO:3; SEQ ID NO: 5; and derivatives thereof; and wherein the second amino acid sequence is an antimicrobial peptide, amphipathic peptide, cationic peptide, hydrophobic peptide, sushi peptide or defensin. In addition, the present invention relates to nucleic acids encoding such polypeptides, vectors comprising such nucleic acids, and corresponding host cells. Finally, the present invention relates to applications of the inventive polypeptides, nucleic acids, vectors, and/or host cells, in particular in the pharmaceutical field.

The present application discloses an anti-microbial coating containing an alkyl urea polyalkylene imine polymer and an anionic polymer. The alkyl urea polyalkylene imine polymer is a polyalkylene imine polymer having at least one alkyl group attached to the polyalkylene imine polymer backbone by way of at least one urea linkage that includes a nitrogen heteroatom on the polyalkylene imine polymer backbone. The anti-microbial coating does not contain heparin or a polymer comprising heparin.

The invention comprises an antiviral film, comprising: a polyethylenimine polymer comprising: (1) repeating monomers comprising nitrogen and (2) a protonated nitrogen form of greater than ten percent of the nitrogens in a group of the repeating monomers, where the antiviral film/the polyethylenimine polymer comprises a charge exceeding 100,000 coulombs, such as where an antiviral function of the film at least meets/is in accordance with the U.S. Environmental Protection Agency's Protocol 01-1A and/or the international PAS2424 durability test. Optionally and preferably, at least one, two, or three counterions from a group of counterions of chloride, formate, acetate, citrate, and iodide are associated with the polyethylenimine polymer in any ratio.

Fabrics, such as employed in air filters, facemasks, garments, or PPE, are coated with pathogen-binding agents, such as chemicals that bind to protein-encapsulated airborne pathogens. Some of these pathogen-binding agents include multifunctional chemicals that bind to the fabrics and to exposed proteins and/or glycans on the pathogens. Some of these pathogen-binding agents include multifunctional silanes. Some of these pathogen-binding agents include multifunctional phosphanes or phosphonates.

Methods of treating a microbial contamination are disclosed. Methods of eliminating or inhibiting proliferation of a target microorganism at a target site are also disclosed. The methods include administering a thermally stable preparation comprising a purified amphiphilic peptide in an aqueous biocompatible solution and administering a buffer to a target site. The peptide has a folding group having a plurality of charged amino acid residues and hydrophobic amino acid residues arranged in a substantially alternating pattern and a turn sequence. The peptide is configured to self-assemble into a hydrogel.
