A DNA-based nanostructure inspired by antibodies as the core of a programmable sensing platform for rapid, single-step diagnostics

A team consisting of current and former members of the ICN2 Nanobioelectronics and Biosensors Group has developed an electrochemical sensor based on a modified DNA scaffold nanostructure able to detect antibodies and proteins in unprocessed biological fluids. It has a Y-shaped architecture that mimics the one of natural Immunoglobulin antibodies. According to the results published in an article in ‘Advanced Functional Materials’, it is selective, specific, and adaptable to the detection of different biomarkers.

A novel nanostructured geometry to control and suppress unwanted GHz mechanical vibrations in materials

As reported today in an article in ‘Nature Nanotechnology’, a team of researchers led by scientists at the Catalan Institute of Nanoscience and Nanotechnology (ICN2) achieved the suppression of mechanical vibrations in a silicon nanostructured membrane by shaping it into a cloverleaf-like pattern. Unwanted vibrations compromise the performance of materials for micro- and nano-electromechanical systems. These results open the way to applications in nanotechnology, optical communications and quantum computing, among others. The publication was accompanied by a News and Views article highlighting the work.
