Mini‐pillar Based Multi‐channel Electrochemical Platform for Studying the Multifactor Silver Electrodeposition

Abstract

Here, we demonstrated a mini‐pillar based multi‐channel electrochemical platform that can efficiently adjust multiple electrochemical deposition parameters in the microdroplet arrays to control and predict the final structures of silver nanomaterials. Each mini‐pillar is capable of anchoring microdroplet to form a separate microreactor, and the electrodes are integrated to achieve a multi‐channel electrochemical electrodeposition platform. We systematically investigated the multiple deposition parameters of silver nanostructures and summarized the relevant experience of electrochemical silver deposition to guide silver nanostructure preparation. Such the mini‐pillar based microdroplet platform provides an approach for further high‐throughput and intelligent nanomaterial fabrication.

A review of metal nanoparticle‐based surface‐enhanced Raman scattering substrates for severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) detection

“…[72][73][74][75][76][77][78][79][80][81] The size and morphology of Ag nanomaterials will determine the SERS properties. [82] The accuracy and sensitivity of detection depend on the structure's morphology. Several parameters such as surrounding temperature, electrolyte composition, electrodeposition time, and potential can be adjusted in order to get different morphology of Ag nanostructures.…”

Electrochemiluminescence Drug Sensor for Acetaminophen using Boron Nitride Quantum Dots as Ru(bpy)32+ Coreactant for Acetaminophen

“…Electrochemiluminescence (ECL) refers to a process in which the luminescent substance forms a high-energy excited state after electrochemical and chemical reactions on the electrode surface, and then relaxes to generate photon emission [1]. The unique luminescence mechanism enables it to combine the high sensitivity and wide dynamic range of chemiluminescence with the controllability, stability, and convenience of electrochemical analysis [2]. According to the response relationship between the test substance and the ECL signal, the quantitative detection of the substance can be realized [3].…”

One-click investigation of shape influence of silver nanostructures on SERS performance for sensitive detection of COVID-19

“…Silver nanomaterials with various nanostructures are widely used for SERS biosensing chips due to their high electrical/thermal conductivities [ [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] ]. These research work indicated that the SERS property of silver nanomaterials are highly dependent on their size and morphology [ 22 ]. However, most of the work is limited to the use of single structure silver nanostructures to construct SERS biosensing chips.…”
