| description | The invention provides a method of preventing or reducing the growth of crystals in a substance which is susceptible to crystal growth in which colloidal particles having an amphiphilic structure, e.g. Janus particles, are contacted with the substance. Colloidal particles suitable for use in the invention include cross-linked, colloidal materials formed from hydrophobic monomers such as acrylates or methacrylates and hydrophilic monomers such as those derived from acrylic and/or methacrylic acid. The colloidal particles find particular use in methods of cryopreservation of biological samples (e.g. cells, tissues or organs), as a texture modifier in frozen food products, in the inhibition of gas hydrate formation, and as scale inhibitors.
La présente invention concerne un procédé permettant d'empêcher ou de réduire la croissance de cristaux faits d'une substance susceptible de croissance cristalline, le procédé consistant à mettre la substance en contact avec des particules colloïdales à structure amphiphile, par exemple des particules Janus. Les particules colloïdales convenant à l'invention comprennent des matières colloïdales réticulées formées de monomères hydrophobes tels que les acrylates ou les méthacrylates, et de monomères hydrophiles tels que ceux dérivés de l'acide acrylique et/ou méthacrylique. Ces particules colloïdales sont particulièrement adaptées à des procédés de cryoconservation d'échantillons biologiques, par exemple de cellules, de tissus ou d'organes, d'une part comme modificateurs de texture, notamment dans le cas de produits alimentaires congelés, pour empêcher la formation d'hydrates de gaz, et d'autre part comme agents antitartre. |
