With these advances, they have achieved high sensitivity and speed; low, non-specific binding with femtomolar DNA and attomolar protein detection, typically in less than 10 minutes.
In the current report, the NRL researchers have adapted FFD assays to detect a protein toxin at concentrations as low as 35 attomolar - over 1000 times more sensitive than existing commercial tests for proteins.
Only highly branched electrodes with fine structuring attained attomolar sensitivity.
