Abstract
Die vorliegende Erfindung betrifft molekuelspezifische Erkennungsstellen aufweisende Nanopartikel sowie Verfahren zu deren Herstellung und Verwendung.

 

WO 200202647 A UPAB: 20020516 NOVELTY - New nanoparticles (I), having molecule-specific recognition sites, have diameter 5-1000 nm and are obtained by forming an emulsion with two immiscible phases, containing monomer(s), molecular specificity-inducing agent(s) (MSIA), emulsifier(s) and optionally initiator(s) and/or crosslinker(s), then carrying out emulsion polymerization. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) the above process for preparing (I); (2) films/membranes (II) composed of particles, obtained by separation of (I) from latices; and (3) the preparation of the films, by filtering or drying latices containing (I). USE - (I) (specifically in microgel form) and (II) are useful in a wide range of chemical and/or biological molecular recognition applications, e.g. in the separation, sensor, analysis, catalysis, material production and medicinal fields. ADVANTAGE - (I) retain their molecular recognition function when incorporated in and/or on films (II). Elastic and mechanically stable, permeable and/or regenerable films (II) can be prepared. (I) are smaller and have more uniform morphology than analogous particles obtained by suspension polymerization; have controllable surface activity properties; and can be obtained in easily processed colloidal form.
