“…An alternative strategy to stabilize metallic NPs, such as AgNPs, consists in using a silica matrix to avoid coagulation and oxidation (Ravindran, Chandran and Khan 2013 ; Tudose et al . 2015a ; Tudose et al . 2015b ).…”

“…Tudose et al . ( 2015a ) developed AgNPs coated with silica (Ag-SiO 2 NPs) and functionalized with vitamins B (biotin, pantothenate and nicotinamide). Ag-SiO 2 -biotin and Ag-SiO 2 -nicotinamide exhibited very low MBEC values (0.97 and 1.95 µg mL −1 , respectively) against S. aureus biofilms in vitro , revealing a higher antibiofilm activity than nonfunctionalized Ag-SiO 2 NPs.…”

Staphylococcus aureus (S. aureus) is considered by the World Health Organization as a high priority pathogen for which new therapies are needed. This is particularly important for biofilm implant-associated infections once the only available treatment option implies a surgical procedure combined with antibiotic therapy. Consequently, these infections represent an economic burden for Healthcare Systems. A new strategy has emerged to tackle this problem: for small bugs, small particles. Here, we describe how nanotechnology-based systems have been studied to treat S. aureus biofilms. Their features, drawbacks and potentialities to impact the treatment of these infections are highlighted. Furthermore, we also outline biofilm models and assays required for preclinical validation of those nanosystems to smooth the process of clinical translation.

“…119 Immobilization of various vitamins including nicotinic acid, pantothenic acid and biotin on the surface of amine-modied Ag@SiO 2 was accomplished using N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline (EEDQ) as a coupling agent. 120 Europium complexes were graed onto the surface of Au@SiO 2 via the condensation of siloxane groups of N-(4-benzoicacidyl), N-(propyltriethoxysilyl) urea (RABI) followed by further reaction with europium(III). 121,122 Xu et al developed core-shell uorescent nanoparticles Ag@SiO 2 @SiO 2 -RuBpy that were used for the uorescence detection of prostate specic antigen (PSA) which is a tumor marker for the diagnosis of prostate cancer.…”

“…The structure of the polymer can be skillfully controlled by adjusting the graft density, composition, and feed ratio of the polymer on particle surface [17]. The silica/polymer hybrids are widely used in the fields of hydrophobic coatings [18], biological materials [19], protein-resistance coatings [20], and antioxidant hybrid materials [21,22]. Typically, the SI-ATRP approach is one common active controlled radical polymerization technique to obtain silica/polymer hybrid materials [16].…”

A series of tem-responsive and protein-resistance property silica-di-block polymers SiO2-g-PMMA-b-P(PEGMA) hybrids are synthesized with methyl methacrylate (MMA) and poly (ethylene glycol) methyl ether methacrylate (PEGMA) by the surface-initiated atom transfer radical polymerization (SI-ATRP). The morphology in tetrahydrofuran (THF) solution, lower critical solution temperature (LCST), surface morphology, bovine serum albumin (BSA)-resistance property, and thermal stability of nanoparticles were analyzed. The results of 1H-NMR, GPC, and TEM prove that the silica-di-block hybrids have been obtained. The silica-di-block hybrids shows the LCST (52–64 °C) in aqueous solution. The hybrid films casted by THF present distributed uniform granular bulges and the film surface is relatively smooth (Ra = 15.4 nm ~ 10.5 nm). The results of QCM-D showed that only a small amount of BSA protein(△f = 18.6 ~ 11.8 Hz) was adsorbed on the surface of the films. The result of XPS also demonstrated that only a small amount of BSA protein was absorbed onto the surface of the film (N% = 1.86). The TGA analyses indicate that the thermal decomposition temperature of hybrids is 288 °C. Thus, it is suggested that the hybrids are served as a suitable coating with BSA resistance property and thermal stability.
