Abstract: The invention concerns supports or receptacles for solubilized or suspended biological entities whereof the walls are made of plastics surface-treated by an electromagnetic plasma followed by a polymer deposition. It can be in the form of tubes or multiple-well plates. It provides among other things the possibility of storing, transferring and performing reactions in the context of microassays of biological entities, more particularly the prion protein, with enhanced sensitivity.

Abstract: The invention relates to bioactive boxes for cellular cultures comprising a bilayer which is arranged on the bottom of said boxes and provided with an internal primary layer made of hydroxypropylmethylcellulose, or polyvinyl alcohol (PVA) and an external bioactive layer made of carboxypropylmethylcellulose. Said invention also relates to the use of the inventive boxes for carrying out methods for studying cellular ageing, cellular differentiation and apoptosis, method s for screening anti-ageing molecules, methods for screening antitumoral molecules, methods for in vitro diagnosis of the antitumoral molecule malignancy and consequently methods for in vitro prognosticating tumors or for study methods related to researches on signalling controlling morphology, bioadhesion, cellular proliferation and intercellular communications.

Abstract: A method for reducing the contamination properties by micro-organisms of a surface made of a mineral material, the surface having an area of at least 0.1 m2, the method including the following steps: a) application, onto the surface to be treated, of a layer of a solution or of an aqueous suspension of a hydrophilic polymeric material; b) drying the surface processed at the step a), for obtaining a surface covered with a layer of the hydrophilic polymeric material.

Abstract: The invention concerns a semipermeable chamber for encapsulation of cells producing at least a biological substance of interest, characterised in that it consists of a porous polycarbonate biocompatible film modified at the surface by generated polar sites and covered with at least a layer of hydrophilic polymer.
