Dissipative particle dynamics simulation study on ATRP-brush modification of variably shaped surfaces and biopolymer adsorption

“…14,15 Therefore, a controlled surface modification of the particles could be crucial to several biomedical applications. [16][17][18][19][20] There are numerous reports demonstrating the importance of surface modification of MPs such as polymeric cup-shaped particles using various techniques such as solvent evaporation, 13 vapor deposition, 21 mini-emulsion, 22,23 and microfluidics. 24 Among the numerous applications of surface-modified particles, the immobilization of biopolymers (e.g., enzymes) has been getting enormous attention in the last decade due to its use in biocatalysts, food processing, drug delivery, textile manufacturing, biosensors, and so on.…”

Protein Patterning on Microtextured Polymeric Nanobrush Templates Obtained by Nanosecond Fiber Laser

“…[21,22] In order to micropattern polymer modified surfaces with feature sizes in micrometer level, ultrathin polymeric films on solid surface would be highly desirable because of their small interacting volumes which ultimately produces miniaturized pattern with microscale feature size. [23] Ultrathin polymeric films are generally produced by surface initiated polymerization and referred as polymer brush, which are surface tethered polymeric chains through one end of the chain, [24,25] a promising tool to alter surface chemistry and morphology of the underlying substrate for applications ranging from membrane sensors, biosensors, cell adhesion, biomolecule adsorption etc. [25][26][27][28][29][30][31][32] Nanometer thick polymer brushes display superb robustness owing to their covalent conjugation to the substrate and they also uniformly spread over the substrate with low surface roughness, thus presumably endowing excellent control over the feature size while patterning via laser ablation technique.…”

An ideal catalyst carrier: patchy nanoparticles with dual functional domains of substrate enrichment and catalysis

“…Anisotropic geometry is known to be entwined with various parameters, and thus the particles with anisotropic structures have significant research value in terms of their physical, chemical, and physiological properties. [1][2][3][4][5][6][7][8] Among the various types of anisotropic structures, patchy micro-nano particles, including Janus particles, [9][10][11][12][13][14][15][16][17][18] are a special class of anisotropic particles, which are defined as particles with precisely controlled patches of varying surface and interaction properties. 19,20 The diversity in shape, composition and polarity makes patchy particles have excellent physical and chemical properties different from other types of anisotropic particles, and important progress has been made in their research and application, such as in the fields of colloidal molecular controllable assembly and its visualization, 21 emulsification, 22 biosensors 23 and others.…”
