Bioinspired superwettable electrodes towards electrochemical biosensing

“…[37][38][39] The electrochemical sensing interface is crucial in electrochemical biosensors and directly affects the biosensing sensitivity, spec-icity, stability, and response dynamics. [40][41][42][43][44][45] Advantages that superwettable materials bring to electrochemical biosensors include, but are not limited to, behaving as biocompatible substrates for biomolecule immobilization, enlarging the active electrochemical areas, intelligent liquid management, favoring the enrichment of target biomolecules, and accelerating the desorption of products. [46][47][48] Most superwettable electrodes are nanostructured materials with high roughness, increasing the active electrode area dramatically.…”

Anti-Oil-Adhesion Property of Superhydrophilic/Underwater Superoleophobic Phytic Acid-FeIII Complex Coatings

“…In recent years, superhydrophilic/underwater superoleophobic surfaces with water contact angles (WCAs) lower than 10° and underwater oil contact angles (underwater OCAs) higher than 150° have received considerable attention due to their excellent anti-oil-adhesion property. , Superhydrophilic surfaces typically possess superior underwater oleophobicity due to their adequate surface roughness and high surface energy. , A large number of hydrophilic groups present on the superhydrophilic surface allow water molecules to be captured in their micro-/nanostructures to create a strong hydration barrier to inhibit oil adhesion. , Numerous techniques, such as electrodeposition, layer-by-layer assembly, chemical etching, and hydrothermal treatment, have been employed to produce superhydrophilic surfaces. Inspired by the excellent oil resistance of natural biological surfaces, many innovative antifouling surfaces have been established by modifying surfaces with hydrophilic materials such as metal oxides, nanocellulose, polyelectrolytes, metal–organic frameworks, and hydrophilic nanoparticles .…”

Non-Cyanide Thick Silver Electrodeposition Base on Instantaneous Nucleation for 3D Microstructures with High Performance

“…[4][5][6][7] Particularly, metallic silver (Ag) exhibits great application potential due to its high electrical/thermal conductivity, and excellent biocompatibility, such as communication, biomedicine and thermal engineering. [8][9][10][11][12] Presently, significant progress has been achieved in non-cyanide Ag electrodeposition technology, mainly focusing on the development of Ag electroplating bath containing alternative ligands (5,5dimethylhydantoin, Iodide ions, etc) to fabricate Ag films or Agbased composite films. [13][14][15][16][17][18] Ag electrodeposition allows the growth of certain thickness of Ag-plated structures on a patterned template at cost-effectiveness.…”
