Small DNA additives to polyelectrolyte multilayers promote formation of ultrafine gold nanoparticles with enhanced catalytic activity

Application of different Nanocatalysts in industrial effluent treatment: A review

“…A bottlebrush polymer tightly linked on a solid core of PS was also investigated as an Ag nanoparticle carrier platform. However, the synthesis method is complicated, which can lead to high costs and difficulties in raw materials personnel, and time, restricting broad realistic implementations [113,114].…”

Recent Advances in Hybrid Biomimetic Polymer-Based Films: from Assembly to Applications

“…Besides gene delivery and sensing of nucleic acid, PE-DNA film has been reported as a catalytic matrix for the synthesis of metal NPs. Due to the intrinsic affinity of DNA for transition metal ions, ionic gold has been efficiently reduced inside the DNA-based multilayer, e.g., PSSNa/poly(allylamine hydrochloride) (PAH)/DNA [36] or poly(diallyldimethylammonium chloride) (PDADMAC)-DNA [49]. In the latter case, catalytically active AuNPs, sized between 2 and 4 nm, have been uniformly distributed within the PE membrane, which, at the same time, has acted as a scaffold matrix locally immobilizing the NPs and thus preventing their aggregation.…”

“…For each system, the assembly approach has been presented, in particular layer-by-layer, bottom-up, and top-down (grafting "from" and grafting "to", respectively), Langmuir-Blodgett and Langmuir-Schaefer methods, and some of the analytical methods commonly utilized for characterization of such films have been mentioned. The review has further exemplified their distinct properties and the properties-related applications for the development of biosensors [17][18][19][20][21][22][23][24][25][26][27][28][29][30], drug delivery platforms [16,[31][32][33][34][35][36][37][38][39][40][41][42][43], cell culture platforms [44,45], biomimicry [46,47], bioelectronic devices, e.g., [48], catalytic matrices [49][50][51], biomimetic lubricants First, we have described biomimetic hybrids based on polyelectrolytes and diverse biomacromolecules, natural polymers, and nanoparticles, followed by the presentation of solid-supported films based on polymer brushes produced either via bottom-up or top-down approach. Next, polymer-lipid tethered and cushioned composite films have been discussed with respect to their composition and properties.…”

Due to the aforementioned, this work has presented, in a comprehensive manner, multiple approaches to the synthesis, processing, and applications of hybrid biomimetic films based on various polymer species, which, in our opinion, would be interesting for both the specialists in the ...…”

Investigation on Stranski–Krastanow (SK) Growth Mode of Ag Coating in Cu/Ag Core-Shell Composites

“…Precious metals such as gold, platinum, and palladium are widely used in organic synthesis and the fuel cell [1][2][3][4]. The synthesis and surface modification of nano precious metal particles has become one of the hot topics in the catalytic field.…”
