Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 88 words
A method for producing a functional organic thin film material comprising the steps of: (a) forming a water insoluble organic thin film on a support; (b) coating on said water insoluble organic thin film by a casting method, a composition containing at least one precursor selected from a group consisting of a nitrene precursor and a carbene precursor; (c) depositing by absorption a bioactive protein on said water insoluble organic thin film; and (d) exposing said bioactive protein adsorbed on said water insoluble organic thin film to light.
Claim 2
Independent Claim 88 words
A method for producing a functional organic thin film material comprising the steps of: (a) forming a water insoluble organic thin film on a support; (b) coating on said water insoluble organic thin film by a casting method, a composition containing at least one precursor selected from a group consisting of a nitrene precursor and a carbene precursor; (c) depositing by absorption a bioactive protein on said water insoluble organic thin film; and (d) exposing said bioactive protein adsorbed on said water insoluble organic thin film to light.
Claim 3
Dependent Claim 29 words
