Deformable platforms for biological assays
A platform for biological assays includes a base substrate providing structural support to the platform, at least one surface of the base substrate coated with position markers, a first deformable layer positioned on top of the base substrate, and a second deformable layer positioned on top of the first deformable layer, the second deformable layer embedded with deformation markers.
1. A platform for biological assays, comprising:
a base substrate providing structural support to the platform, at least one surface of the base substrate coated with position markers and a deformable layer positioned on top of the base substrate, wherein said deformable layer comprises a plurality of detectable deformation markers embedded throughout or adherent to an exposed surface of said deformable layer; and
a top plate positioned on top of the deformable layer, the top plate having multiple through holes and plasma-clean bonded to the deformable layer such that the through holes form well walls and portions of a surface of the deformable layer forms well bottoms, wherein the top plate is water impermeable and the first deformable layer is water impermeable to prevent cross contamination between wells.
2. The platform of claim 1 , wherein said deformation markers comprises fluorescent beads.
3. A platform for biological assays, comprising:
a base substrate providing structural support to the platform,
a first deformable layer positioned on top of the base substrate; and
a top plate positioned on top of the first deformable layer, said top plate comprising multiple through holes,
wherein said first deformable layer is plasma-clean bonded to said top plate such that the through holes form well walls and portions of a surface of the deformable layer forms well bottoms, wherein the top plate is water impermeable and the first deformable layer is water impermeable to prevent cross contamination between wells, and wherein the Young's modulus of said first deformable layer and said top plate are different.
