Amplification trick increases sensitivity of water toxin detection by 10 times
The latest version of the sensing platform ROSALIND is 10 times more sensitive than its predecessor, opening the possibility for the system to be applied to the detection and monitoring of nucleic acid and bacterial diseases in the human body. Credit: Northwestern University Electric instruments can function unplugged, but they sound better when connected to an amplifier. Similarly, low concentrations…

New manufacturing strategy improves graphene airgel sensitivity and durability for human-machine interfaces
Graphene airgel shows potential as a high-performance pressure sensor in human-machine interfaces due to its mechanical properties and electrical conductivity. Anisotropic chitosan graphene oxide (CS-GO) airgel metamaterials with highly ordered honeycomb microstructures were synthesized using conventional directional freeze casting. Subsequently, cross-linked chitosan and reduced graphene oxide (CCS-rGO) aerogels with buckled networks achieved by heating and post-crosslinking at 180 °C for…
