Abstract
The invention relates to methods for treating ceramic surfaces to decrease their wettability by aqueous solutions. One method involves polishing the ceramic surface until wettability is decreased, and a second method involves a silane heat treatment. Both methods can be used to produce ceramic supports for IEF and electrophoresis gels, as well as microarray plates.
Claims52
A method for modifying a ceramic surface, comprising polishing the surface with an abrasive under conditions sufficient to decrease the wettability of the ceramic surface by aqueous solutions.
A method for modifying a ceramic surface, comprising contacting the ceramic surface with a silane and heating for a sufficient time at a sufficient temperature to decrease the wettability of the ceramic surface by aqueous solutions.
A method for modifying a ceramic surface, comprising,
- (a) contacting the surface with an alkyl-containing silane;
- and
- (b) heating the surface and the alkyl-containing silane under conditions sufficient to react at least a portion of the hydroxyl groups on ceramic surface with the alkyl-containing silane.
A ceramic material comprising a surface that has been treated by polishing the surface with an abrasive under conditions sufficient to decrease the wettability of the ceramic surface by aqueous solutions.
A ceramic material comprising a surface that has been treated by contacting the ceramic surface with a silane and heating for a sufficient time at a sufficient temperature to decrease the wettability of the ceramic surface by aqueous solutions.
A sample holder for chemical analysis, comprising a ceramic surface having a contact angle of greater than about 40 with an aqueous solution comprising about 6 to about 9.8 M urea.
