Abstract

Un dispositivo biomédico, que comprende: (a) un material de nucleo que tiene una pluralidad dispersa de cargas transitorias o permanentes sobre ocerca de la superficie del material, en donde el material de nucleo tiene una densidad de cargasu perficial relativamente baja; (b) un recubrimientosuperficial que incluye un material poli-ionico que se enlaza al material de nucleo. Un método para su produccion, un lente oftálmico, un molde parafabricar un artículo, un método para fabricarun artículo, un método para alterar la superficie de un artículo y un producto biomédico. Un métodopreferido involucra recubrir por rociado un material policationico sobre un lente de nucleo, enjuagar y secar el lente, seguido por unrecubrimi entorociado de un material polianionico, enjuagar y secar. El proceso de recubrimiento se puede aplicar una pluralidad de veces para lograr unrecubrimiento de multiples capas sobre la superficie del lente. Una modalidadparticularmente p referida es un lente de contacto que comprende un nucleohidrofobico altamente permeable al oxígeno con 5 a 20 bicapas de materiales poli-ionicos hidrofílicos.
