A composition comprising:
- a biocompatible solid support comprising a hydrogel, polymer, sugar based biomaterial, protein or poly(amino-acid), each of which is modified;
- and at least one binding agent covalently linked to the biocompatible solid support via a linker, wherein at least one binding agent is one of a pair of binding agents capable of a click reaction, wherein the click reaction is a reaction between a maleimide and a thiol.
A composition comprising:
- a biocompatible solid support comprising a hydrogel, polymer, sugar based biomaterial, protein or poly(amino-acid), each of which is modified;
- and at least one binding agent covalently linked to the biocompatible solid support via a linker, wherein at least one binding agent is one of a pair of binding agents capable of a click reaction, wherein the click reaction is a reaction between a maleimide and a furan.
A method for delivering an effective amount of a pesticide to an application environment in a plant growth medium, comprising the steps of:
- (a) contacting a biocompatible solid support with a first binding agent, wherein the biocompatible solid support is thereby linked to the first binding agent, to obtain a receptive biocompatible solid support;
- (b) applying to a plant growth medium the receptive biocompatible solid support;
- (c) contacting the receptive biocompatible solid support with the conjugating agent comprising the pesticide linked to the second binding agent wherein the link comprises a cleavable linkage to the pesticide, such that the first and second binding agents link to one another upon contact, thereby linking the pesticide to the biocompatible solid support, to obtain the controlled release system;
- wherein the cleavable linkage to the pesticide in the controlled release system cleaves, and therefore the controlled release system controllably releases an effective amount of pesticide to the application environment.
