The methods of manufacturing molds from shape memory materials and molds made thereby, in accordance with the present invention, provide numerous advantages for molding castable composite parts. The initial mold cost is low enough to accommodate economical production of as few as a single part incorporating high surface definition and intricate three dimensional detail. The preferred methods and molds made thereby are transparent, thereby, curing of the corresponding part by ultra-violet and infra-red light is made possible, as well as, visual inspection during injection and curing of the given resin. Removal of the cured part from within the mold is simplified.

A convenient way of isolating individual cells permits individual analysis of their contents. A capture support for individually capturing cells of interest comprises a first surface including at least one well sized to accommodate an individual cell, wherein the support is made of a differentially permeable material which permits transfer of a solvent and any low molecular weight species through the support from a second surface of the support to a well, but which is substantially impermeable to biopolymers. Single cells are captured, their contents are released, and the contents of individual cells are then analysed within a chamber containing suitable analytical components e.g. immobilised nucleic acid probes, immobilised antibodies, etc. Analysis of a single cell's genome, transcriptome, proteome, etc. thus becomes possible.

A method for rapidly heating a mold cavity to a predetermined temperature preferably above the softening or melting temperature of the molding material prior to and during the molding stage thereby increasing moldability and improving quality of molded parts. The mold cavity is formed by two metallic halves on which high-frequency electric current is applied and an electric circuit involving the two halves is formed. Due to the proximity effect, the electrical current flows on the inner surfaces of the two cavity halves, thus rapidly heating the mold cavity. Proper use of insulation behind the cavity surface helps increase heating efficiency. Conformal on-off cooling channels provide both thermal insulation during the heating phase and rapidly cooling of the molded article during the cooling phase.
