摘要:The invention discloses and claims a new class of chemical compositions with ideal sunscreen properties. The chemical composition comprises spherical particles between 200 nm and 10 microns in diameter prepared by an emulsion polymerization of tetraalkoxysilanes or organotrialkoxysilanes or organobridged trialkoxysilanes with a dye monomer bearing two or more alkoxysilyl groups attached to the bridging chromophore. The resulting spheres absorb ultraviolet light. The dye can be any organic chromophore capable of receiving multiple trialkoxysilyl groups resulting in multipoint covalent attachment that precludes leaching of the dye from the spheres. The formic acid-toluene-monomer emulsion polymerization allows for large-scale (>100 gram) synthesis of monodisperse particles under acidic, non-aqueous conditions without surfactants. The particles less than 1 micron in diameter are smooth as talc to the touch and will provide a smooth formulation for sunscreen creams or lotions.

摘要:The present invention relates to substrates comprising a crosslinked network of covalently attached antimicrobial and/or antibiofouling polymers. The crosslinked network of antimicrobial and/or antibiofouling polymers acts highly efficiently against pathogens, e.g. bacteria and fungi. Both the antimicrobial and the antibiofouling cross-linked polymer networks are preferably better resistant to mechanical damage than simple surface-immobilized polymer monolayers. The antimicrobial and/or antibiofouling polymers of the crosslinked network are preferably obtained by ring opening metathesis polymerization (ROMP) and exhibit a molecular weight of preferably more than 30,000 or even 100,000 g mol−1. The crosslinked network of antimicrobial and/or antibiofouling polymers is preferably covalently attached to the surface of a substrate, e.g. an implant, a medical device, medical equipment or a (tissue-supporting) biomaterial, etc. The present invention is also directed to uses of crosslinked networks of antimicrobial and/or antibiofouling polymers as defined herein, e.g. for coating a surface of a substrate, and to methods therefore.

摘要:Silanation compositions containing a mixture of two or more silanation reagents, where at least one silanation reagent includes a functional group capable of supporting polymer synthesis and at least one silanation reagent includes no functional group capable of supporting polymer synthesis are useful in modulating the active site density and hydrolytic stability of a surface. These compositions are particularly useful in silanating a surface prior to preparation of a polymer array and provide for increased hybridization results.
