Abstract
The present invention relates to a method for forming functional materials, and particularly cross-linked active matrices, for regulating, limiting and blocking oxygen in in vitro cell culturing and packaging for food and beverages, onto a target substrate, as well as to functional substrates obtainable from said methods and kits to be used in said methods.
Claims26
A method of forming a cross-linked active matrix onto a substrate, comprising the following steps:
- (i) providing a first fluid composition comprising at least one cross-linking agent;
- (ii) providing a second fluid composition comprising one or more active molecules or biomolecules capable of cross-linking with said cross-linking agent;
- (iii) depositing by means of a printing or coating technique the first and second compositions on top of each other onto said substrate by means of simultaneous or subsequent deposition;
- or (iii′) premixing said first and second compositions followed by depositing the resulting pre-mixture onto said substrate;
- and
- (iv) gelling the compositions or pre-mixture deposited in step (iii) or (iii′) so as to obtain said cross-linked active matrix onto the substrate.
