Electrochemical removal of anodic aluminium oxide templates for the production of phase-pure cuprous oxide nanorods for antimicrobial surfaces

Abstract

Highlights Chemical removal of anodic aluminium oxide templates can damage embedded structures. Anodic aluminium oxide templates were used to grow cuprous oxide nanorod arrays. Electrochemical removal technique prevented reduction of cuprous oxide nanorods. Reported procedure is useful in production of antimicrobial surfaces.

Boosting plasmon-enhanced electrochemistry by in situ surface cleaning of plasmonic nanocatalysts

“…24 Based on the proposed strategy, the Cu 2 O shell can be selectively removed without altering the properties of the Au NC core. 25,26 Specifically, the obtained Au@Cu 2 O NCs were deposited onto the electrode surface and the surface cleaning process was carried out by in situ CV scanning (or linear scanning) from −0.15 V to 0.7 V in an alkaline environment, which allows for the subsequent plasmon-enhanced electrochemical studies. During the first cycle in NaOH, the featureless CV curve is attributed to Cu 2 O (Fig.…”

“…As the cycles increase, Cu 2 O gradually decomposes through transforming into HCuO 2 − by electrooxidation. 25 Consequently, the Cu 2 O shell grows thinner and the Au core begins to dominate in the electrochemical process (Fig. 3A, green curve).…”

Does freezing induce self-assembly of polymers? A molecular dynamics study

“…Owing to the ease of scaling and advanced biomimicking capabilities, self-assembly is widely used in the field of biomedicine, 1 drug delivery, 8 tissue engineering, catalysis, 9,10 fabrication of nanomaterials, 2,13 photovoltaics, 9 and energy storage devices. 14 There are various modes of self-assembly, namely, template removal, 15,16 evaporation-induced self-assembly (EISA), 17,18 polymerization-induced self-assembly (PISA), 7,19,20 external field (photovoltaic, 21 electric, 22 magnetic or gravitational 23 )-assisted self-assembly, freezing induced self-assembly (FISA), [24][25][26][27][28] etc. Most of these aforementioned techniques require the use of some physical or chemical treatment, which renders them unsuitable for biological and biomedical applications.…”
