While the evolution of hydrogen gas is often a troublesome process accompanying electrodeposition, this feature can be exploited to template the growth of highly porous surfaces. This process, known as the dynamic hydrogen bubble template (DHBT) method, can be utilised to create a wide range of macroporous films with nanostructured pore walls. This feature article presents an overview of the status of the DHBT technique, highlighting preparation techniques and emerging applications.
We demonstrate a simple electrochemical route to produce uniformly sized gold nanospikes without the need for a capping agent or prior modification of the electrode surface, which are predominantly oriented in the {111} crystal plane and exhibit promising electrocatalytic and SERS properties.
Using a state of the art nano-electrochemical technique, we show that a single virus ‘tagged’ with silver nanoparticles can be rapidly detected in real time at the single virus level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
