Affinity contact printing

A different example of affinity contact printing was shown by Jang et al.114 This multistep approach relies on the modification of a PDMS stamp with aminosilanes and... 

Figure 14.14 Affinity contact printing (aCP)113 relies on inking the surface of a PDMS stamp with antigens as capture molecules, which allows subsequent binding of selected antibodies from a solution containing mixtures of proteins.

Heat transfer printing- A method of printing fabric of polyester or other thermoplastic fibers with disperse dyes. The design is transferred from pre-printed paper onto the fabric by contact heat which causes the dye to sublime. Having no affinity for paper, the dyes are taken up by the fabric. The method is capable of producing well-defined, clear prints. 

Connections made with insulating adhesives free of fillers are electrically conductive if the partners are in contact with each other in adhesive no thicker than the surface roughness (< 10 pm). In principle the process is very similar to that of anisotropic adhesive gluing. The glue is applied by a dispenser or by print application of a paste. The electrically nonconductive adhesive can be applied allover across multiple connections. This implies low requirements for the process as such and therefore good affinity for fine-pitch applications. Once the partners to be joined have been positioned, the adhesive cures under pressure and temperature within a matter of seconds.
