Abstract
The present invention generally provides an improved transfer film having multiple layers for laser micro-capture of a sample. The transfer film for laser micro-capture includes distinct layers for expansion and adhesion in order to optimize the performance of the transfer film. A transfer film including a spring-back layer is also disclosed.
Claims17
A method for laser micro-capture comprising:
- providing a sample,
- placing the sample in the optical path of an optical system,
- placing a transfer film within the optical path of the system;
- the transfer film
- comprising at least one energy absorbing substance and, at least one expansion layer and at least one adhesive layer;
- the adhesive layer being located between the expansion layer and the sample selecting a portion of the sample for micro-capture;
- exposing the at least one energy absorbing substance to energy capable of activating the transfer film resulting in expansion of the expansion layer to exert a force upon the adhesive layer such that a selected portion of the sample adheres to the adhesive layer for micro-capture.
4 more elements
A transfer film for laser micro-capture of a sample comprising:
- at least one expansion layer, and
- an outer adhesive layer coupled to one side of the expansion layer;
- the adhesive layer being located between the expansion layer and the sample for micro-capture;
- the expansion layer being adapted to absorb energy incident upon the transfer film and to expand to exert a force upon the adhesive layer such that the adhesive layer is deflected towards a selected portion of the sample;
- the adhesive layer being adapted to adhere to the selected portion of the sample for micro-capture.
