Particle nanoparticle polymer printing

Numerous electrochemical platforms have been developed for DNA detection, including direct electrochemistry of the DNA bases [5], electrochemistry of different polymer-modified screen-printed chips [6], electrochemistry of DNA-specific redox indicator molecules or enzymes [7,8], electrochemistry of signal amplification with nanoparticles (NPs) such as gold, silver or magnetic particles [9,10], and dsDNA r-stacked mediated charge transport chemistry [4, 7,11,12]. 

Another way to obtain a flexible textile compatible strain sensor is based on conductive polymer composites (Cochrane et al., 2007). Carbon black nanoparticles are captured in a thermoplastic elastomer matrix that can be printed onto a textile substrate (Fig. 2.4). Upon strain deformation, the distance between the particles will change and an electrical current will pass less easily through the composite, resulting in a resistance change.
