Abstract
The present invention relates to substituted cellulose acetates and methods of use thereof. One embodiment of the present invention provides a coating having a substituted cellulose acetate having a polar substituent that has an oxygen atom covalently bonded to a nonmetal selected from the group of sulfur, phosphorus, and boron; wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate.
Claims29
A coated seed comprising:
- a seed having a coating that comprises a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of:
- sulfur, phosphorus, boron, and chlorine;
- wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate.
A coated pharmaceutical composition comprising:
- a pharmaceutical composition having a coating that comprises a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of:
- sulfur, phosphorus, boron, and chlorine;
- wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate.
A kit for detection of an analyte comprising:
- a reporter molecule having a coating that comprises a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of:
- sulfur, phosphorus, boron, and chlorine;
- wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate.
A coated stent comprising:
- a stent having an outer coating layer that comprises a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of:
- sulfur, phosphorus, boron, and chlorine;
- wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate;
- and
- an inner coating layer that comprises a pharmaceutical composition.
A method comprising:
- coating a seed with a coating comprising a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of:
- sulfur, phosphorus, boron, and chlorine;
- wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate.
A method comprising:
- coating a pharmaceutical composition with a coating comprising a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of:
- sulfur, phosphorus, boron, and chlorine;
- wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate.
