  Nanoporous gold supported cobalt oxide microelectrodes as high-performance electrochemical biosensors

  Metal oxides are proposed as replacements for expensive enzymes in electrochemical biosensors, but their wide use is currently limited by poor electronic conductivity. Lang et al. engineer the nanoarchitecture of electrodes to reduce contact resistances, which leads to an ultrahigh sensitivity to glucose.

  Low-concentration mechanical biosensor based on a photonic crystal nanowire array

  Nanomechanical resonators are attractive as ultra-low concentration sensors of biomolecules, as their small scale allows for sensitive mass detection. Here, using a nanowire array as part of a photonic crystal, such a device is presented for light trapping, absorption and low-concentration sensing.

  Motion-based DNA detection using catalytic nanomotors

  Synthetic nanomotors convert chemical energy into motion. Here, they have been implemented in a motion-based assay that allows specific DNA and ribosomal RNA detection. The technique is fast, simple and sensitive, and the concentration-dependant distance signals of the magnetically aligned nanomotors are detected by optical microscopy.
