We reported a surface charge sensitive suspended nanoparticle crystal (S-NPC) as a promising nanofluidic-based sensing strategy. In the S-NPC, interspaces among nanoparticles construct a nanochannel network and provide nanofluidic electrokinetic properties. When electric double layers inside the interspaces are overlapped, conductance across the S-NPC will be directly related to the surface charge density of the nanoparticles, offering an approach to sense the surface charge. The enormous… CONTINUE READING
