A colorimetric logic gate based on free gold nanoparticles and the coordination strategy between melamine and mercury ions
A colorimetric logic gate based on free gold nanoparticles is presented with melamine and Hg2+, as well as its colorimetric detection of Hg2+ with good selectivity and sensitivity.
Gold nanotip array for ultrasensitive electrochemical sensing and spectroscopic monitoring
A gold nanotip array platform with a combination of ultrasensitive electrochemical sensing and spectroscopic monitoring capability is reported. Adenosine triphosphate is detected down to 1 pM according to the impedance ...
Bioengineered tunable memristor based on protein nanocage
Bioengineered protein-based nanodevices with tunable and reproducible memristive performance are fabricated by combining the unique high loading capacity of Archaeoglobus fulgidus ferritin with OWL-generated nanogaps. By ...
Efficient Ag@AgCl cubic cage photocatalysts profit from ultrafast plasmon-induced electron transfer processes
Photon-coupling and electron dynamics are the key processes leading to the photocatalytic activity of plasmonic metal-semiconductor nanohybrids. To better utilize and explore these effects, a facile large-scale synthesis ...
