“…The Rutherford backscattering spectrometry (RBS) spectra were measured on a 3 MV Tandetron MC 4130 accelerator using 2.0 MeV 4He + ions at a laboratory scattering angle of 170° in the Cornell geometry. The Ultra-Ortec PIPS detector solid angle was 2.612 mSr, the spectrometer energy resolution for 2.0 MeV 4He + ions was defined at full width at half maximum (FWHM) = 12 keV and the beam spot area on the sample was 1x1 mm 2 . The typical beam current was 5 nA.…”

“…Nanoscale-sized metal particles are indispensable in numerous industrially important applications such as catalysis [ 1 , 2 , 3 ], healthcare (targeted cancer therapy [ 4 ], antibacterial treatment of medical devices [ 5 , 6 ], biochips [ 7 ], drug delivery [ 8 ]), cosmetics [ 9 ], and the textile industry [ 10 , 11 ]. The typical characteristics of materials exploitable in these applications are the large interaction area between active components (nanoparticles (NPs)) and the environment with simultaneous minimal leakage or targeted release of those active components from the reaction/interaction area into surroundings.…”

The properties of materials at the nanoscale open up new methodologies for engineering prospective materials usable in high-end applications. The preparation of composite materials with a high content of an active component on their surface is one of the current challenges of materials engineering. This concept significantly increases the efficiency of heterogeneous processes moderated by the active component, typically in biological applications, catalysis, or drug delivery. Here we introduce a general approach, based on laser-induced optomechanical processing of silver colloids, for the preparation of polymer surfaces highly enriched with silver nanoparticles (AgNPs). As a result, the AgNPs are firmly immobilized in a thin surface layer without the use of any other chemical mediators. We have shown that our approach is applicable to a broad spectrum of polymer foils, regardless of whether they absorb laser light or not. However, if the laser radiation is absorbed, it is possible to transform smooth surface morphology of the polymer into a roughened one with a higher specific surface area. Analyses of the release of silver from the polymer surface together with antibacterial tests suggested that these materials could be suitable candidates in the fight against nosocomial infections and could inhibit the formation of biofilms with a long-term effect.

“…In the last decade, the world has witnessed tremendous advancements in the field of nanoscience and its applicability in diverse domains, including academics, industry, and medicine. The distinct physicochemical characteristics and high surface area-to-volume ratio of nanoparticles (NPs) make them attractive candidates for the development of biocompatible materials that can be used in industries and clinical settings ( Eisa et al, 2019 ). Metallic NPs with desired properties have been synthesized using several physical and chemical methods; however, these methods are expensive, utilize hazardous chemicals, require high levels of energy, and expel toxic byproducts that are deleterious to the environment ( Patra and Baek, 2015 ).…”

Phyto-Mediated Synthesis of Porous Titanium Dioxide Nanoparticles From Withania somnifera Root Extract: Broad-Spectrum Attenuation of Biofilm and Cytotoxic Properties Against HepG2 Cell Lines

There is grave necessity to counter the menace of drug-resistant biofilms of pathogens using nanomaterials. Moreover, we need to produce nanoparticles (NPs) using inexpensive clean biological approaches that demonstrate broad-spectrum inhibition of microbial biofilms and cytotoxicity against HepG2 cell lines. In the current research work, titanium dioxide (TiO 2 ) NPs were fabricated through an environmentally friendly green process using the root extract of Withania somnifera as the stabilizing and reducing agent to examine its antibiofilm and anticancer potential. Further, X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), transmission electron micrograph (TEM), energy-dispersive X-ray spectroscopy (EDS), dynamic light scattering (DLS), thermogravimetric analysis (TGA), and Brunauer-Emmett-Teller (BET) techniques were used for determining the crystallinity, functional groups involved, shape, size, thermal behavior, surface area, and porosity measurement, respectively, of the synthesized TiO 2 NPs. Antimicrobial potential of the TiO 2 NPs was determined by evaluating the minimum inhibitory concentration (MIC) against Escherichia coli , Pseudomonas aeruginosa , methicillin-resistant Staphylococcus aureus , Listeria monocytogenes , Serratia marcescens , and Candida albicans . Furthermore, at levels below the MIC (0.5 × MIC), TiO 2 NPs demonstrated significant inhibition of biofilm formation (43–71%) and mature biofilms (24–64%) in all test pathogens. Cell death due to enhanced reactive oxygen species (ROS) production could be responsible for the impaired biofilm production in TiO 2 NP–treated pathogens. The synthesized NPs induced considerable reduction in the viability of HepG2 in vitro and could prove effective in controlling liver cancer. In summary, the green synthesized TiO 2 NPs demonstrate multifarious biological properties and could be used as an anti-infective agent to treat biofilm-based infections and cancer.
