A work about paper-based nanobiosensors highlighted by Nature Nanotechnology

An international team led by the ICREA Prof Arben Merkoci reported in ACS Nano new sensing platforms based on bacterial cellulose nanopaper. The Nature Nanotechnology journal selected this work in its Research Highlights section of the August issue.

Paper is light, flexible, inexpensive, biodegradable, and is made from abundantly available materials such as plants and non-pathogenic bacteria found on fruits. These are some of the reasons why the journal Nature Nanotechnology (1) highlighted a work led by the ICREA Prof Arben Merkoci, Group Leader at ICN2, which reported recently in ACS Nano (2) various innovative nanopaper-based optical sensing platforms. The journal also highlights an independent work, led from the Huazhong University of Science and Technology and the University of Maryland, which presented in ACS Nano (3) a transparent-paper-based generator that is powered by applying pressure with a finger.

The text explains how the researchers led by the ICN2 Nanobioelectronics and Biosensors Group created paper that exhibits plasmonic and photoluminescent properties by depositing either gold, silver or upconversion nanoparticles on bacterial cellulose paper. This kind of platforms will prove valuable for displaying analytical information in diverse fields such as diagnostics, environmental monitoring and food safety.
