Patent ID: 8679808

Claim:
A method for fabricating biocomposite, comprising: providing a precursor solution, wherein said precursor solution comprises: a hydrophilic ionic liquid, wherein the hydrophilic ionic liquid is formed by mixing an organic base with a Lewis acid wherein the Lewis acid is not halogenated metal acid, wherein a cationic moiety in said organic base is alkyl or aryl group having the following general equation, wherein R 1 , R 2 , R 3 , and R 4 are selected according to the following table, R 1 R 2 R 3 R 4 CH 3 H CH 3 H C 2 H 5 H C 2 H 5 H CH 3 CH 2 CH 2 CH 2 H CH 3 H (CH 3 ) 2 CHCH 2 H CH 3 H CH 3 CH 2 CH 2 CH 2 H C 2 H 5 H CH 3 H CH 3 OCH 2 CH 2 H CH 3 H CF 3 CH 2 H CH 3 CH 3 C 2 H 5 H CH 3 CH 3 CH 3 CH 2 CH 2 H C 6 H 6 CH 2 CH 3 CH 3 CH 2 CH 2 H C 6 H 6 CH 2 CH 3 CH 3 CH 2 CH 2 CH 2 H C 6 H 6 CH 2 CH 3 (CH 3 CH 2 )(CH 3 )CH H C 6 H 6 CH 2 CH 3 CH 3 CH 2 CH 2 CH 2 CH 2 H CH 3 H C 2 H 5 CH 3 C 2 H 5 H C 2 H 5 CH 3 ; a catalyst comprising one selected from the group consisting of alcohol, buffer, and a combination thereof; at least one biomolecule; and at least one alkoxide monomer and/or aryloxide monomer; curing the precursor solution by hydrolyzing and polymerizing said at least one alkoxide monomer and/or aryloxide monomer in the precursor solution to form an aerogel wrapping said at least one biomolecule to form said biocomposite; and extracting hydrophilic ionic liquid from the biocomposite by substituting a solvent for the hydrophilic ionic liquid.
