Assembly of surface-independent polyphenol/liquid gallium composite nanocoatings

Abstract

The development of functional nanocoatings using natural compounds is a hallmark of sustainable strategies in the field of green synthesis. Herein, we report a surface-independent nanocoating strategy using natural polyphenols...

Interactions of Melanin with Electromagnetic Radiation: From Fundamentals to Applications

“…Investigations on phenols started from tannic acid (TA) ,− and have been extended to catechol, pyrogallol (PG), CA, , and GA (Figure a), with other catecholic acids (e.g., pyrocatechuic acid and chlorogenic acid) remaining largely unexplored. Table summarizes the synthesis conditions for metal–phenolic networks.…”

A liquid metal–polydopamine composite for cell culture and electro-stimulation

“…11,12,16–20 Gallium-based droplets are now being routinely investigated as a new type of biocompatible soft platform with unique fluidity and physicochemical properties for biomedical applications and nanomedicine. 10,12,13,21–27…”

“…11,12,[16][17][18][19][20] Gallium-based droplets are now being routinely investigated as a new type of biocompatible soft platform with unique fluidity and physicochemical properties for biomedical applications and nanomedicine. 10,12,13,[21][22][23][24][25][26][27] In principle, biomaterials for cell culture should show excellent in vitro biocompatibility without any harmful byproduct generation and also present suitable surface characteristics to allow cell adhesion and proliferation. [28][29][30] Typically, for cell culture experiments, dense glass or polymer-based supports, permeable gel supports and polymeric meshes are utilised.…”

Patterned Liquid-Metal-Enabled Universal Soft Electronics (PLUS-E) for Deformation Sensing on 3D Curved Surfaces

“…2,33−37 covered with prepatterned masks. 38−40 The transfer printing is achieved by precontrolling the adhesion properties of the 3D surfaces, which can involve applying adhesive coatings 41 or laserassisted deposition. 42−45 However, these methods commonly face limitations, such as complex processes and the requirement for additional processing steps.…”

“…The first strategy involves the direct deposition of the liquid metals onto the target surface including 3D printing, spray printing, and transfer printing. The 3D printing is realized by adhering the liquid metals extruded from microchannels onto the 3D surfaces. ,− Spray printing is implemented by spraying liquid metal microdroplets onto the 3D surfaces covered with prepatterned masks. − The transfer printing is achieved by precontrolling the adhesion properties of the 3D surfaces, which can involve applying adhesive coatings or laser-assisted deposition. − However, these methods commonly face limitations, such as complex processes and the requirement for additional processing steps. For example, 3D printing and adhesive coatings require precise control of the 3D motion platform to manipulate the movement of microchannels.…”
