Abstract
A method of separating particles is provided that includes exposing a selective PDMS adhesive to a particle-contaminated surface, where the selective PDMS adhesive captures particles present on the particle-contaminated surface to form a fouled selective PDMS adhesive, and exposing the fouled selective PDMS adhesive to a PDMS transfer sheet, where particles outside of a desired range are transferred over to the PDMS transfer sheet, where the fouled selective PDMS adhesive retains only the particles of a desired range.
Claims10
A method of separating particles, comprising:
- a. exposing a selective PDMS adhesive to a particle-contaminated surface, wherein said selective PDMS adhesive captures particles present on said particle-contaminated surface to form a fouled selective PDMS adhesive, and
- b. exposing said fouled selective PDMS adhesive to a PDMS transfer sheet, wherein particles outside of a desired range are transferred over to said PDMS transfer sheet, wherein said fouled selective PDMS adhesive retains only said particles of a desired range.
