Abstract
A multiwell plate is described that is used for assaying samples and is made from a plastic upper plate which forms the sidewalls of one or more wells and a glass lower plate which forms the bottom walls of the wells. The plastic upper plate and glass lower plate are attached and bound to one another by an enhanced adhesive. The enhanced adhesive includes an adhesive mixed with an additive that interacts with the adhesive, the plastic upper plate and the glass bottom plate in a manner that strengthens a bond between the plastic upper plate and the glass lower plate. Also described herein is a method for making such multiwell plates.
Claims21
A multiwell plate forming a plurality of sample wells for holding samples to be assayed, said multiwell plate comprising:
- an upper plate that forms sidewalls of the sample wells, said upper plate made from a polymeric material;
- and
- a lower plate that forms bottom walls of the sample wells, said lower plate made from a pyrolized glass, wherein said upper plate was joined to said lower plate by an adhesive mixed with a silane monomer that polymerized to form a compatible network with the adhesive to strengthen a bond between said upper plate and said lower plate, wherein said polymeric material is plasma treated polymeric material after being subjected to a plasma treatment process to create reactive groups that would interact with the silane monomer in said adhesive to further strengthen the bond between said adhesive and said upper plate.
A multiwell plate forming a plurality of sample wells for holding samples to be assayed, said multiwell plate comprising:
- an upper plate that forms sidewalls of the sample wells, said upper plate made from a plasma treated polymeric material;
- and
- a lower plate that forms bottom walls of the sample wells, said lower plate made from a pyrolized glass, wherein said upper plate was joined to said lower plate by an adhesive mixed with a silane monomer that polymerized to form a compatible network with the adhesive to strengthen a bond between said upper plate and said lower plate.
A multiwell plate forming a plurality of sample wells for holding samples to be assayed, said multiwell plate comprising:
- an upper plate that forms sidewalls of the sample wells, said upper plate made from a plasma treated polymeric material;
- a lower plate that forms bottom walls of the sample wells, said lower plate made from a pyrolized glass, wherein said upper plate was joined to said lower plate by an adhesive mixed with a silane monomer that polymerized to form a compatible network with the adhesive to strengthen a bond between said upper plate and said lower plate;
- said silane monomer includes silane functional groups that interact with reactive groups associated with said plasma treated polymeric material to strengthen a bond between said adhesive and said upper plate;
- and
- said silane monomer includes silane functional groups that interact with silane reactive groups associated with said pyrolized glass to strengthen a bond between said adhesive and said lower plate.
A multiwell plate having a plurality of sample wells for holding samples to be assayed, said multiwell plate comprising:
- an upper plate that forms sidewalls of the sample wells, said upper plate made from a plasma treated polymeric material;
- and
- a lower plate that forms bottom walls of the sample wells, said lower plate made from a glass, wherein said upper plate was joined to said lower plate by an adhesive which contained a silane monomer that polymerized within the adhesive to strengthen a bond between said upper plate and said lower plate.
A multiwell plate for use in assaying samples, comprising:
- a frame that forms sidewalls of at least one well, the frame being formed from a plasma treated polymeric material;
- a layer that forms a bottom wall of the at least one well, the layer being formed from pyrolized glass;
- said frame and said layer are attached and bound to one another by an adhesive mixed with a silane monomer that interacts with the adhesive, said frame and said layer in a manner which strengthens a bond between said frame and said layer;
- wherein said pyrolized glass was subjected to a pyrolysis process to free silanol groups that interact with the silane monomer in said adhesive to further strengthen the bond between said adhesive and said layer;
- and
- wherein said plasma treated polymeric material was subjected to a plasma treatment process to create reactive groups that interact with the silane monomer in said adhesive to farther strengthen the bond between said adhesive and said frame.
