The newly revised and expanded second edition provides an updated overview of advances in dental gold alloys and gold nanoparticles for biomedical applications. Building on the foundation of the first edition, the book integrates the latest research, innovations, and clinical perspectives. Dental gold alloys remain a benchmark material in restorative dentistry, offering a desirable combination of …

The optical characteristics of directly deposited gold nanoparticle (AuNP) films were investigated in the newly published work. Four samples were made using Ultrasonic Spray Pyrolysis technology, with AuNP deposition periods on the glass substrate of 15 minutes, 30 minutes, 1 hour, and 4 hours. The morphological characterisation of the formed films revealed that the earliest …

Gold nanoparticles (AuNPs) and hydroxylated fullerene water complex (3HFWC) may be used as novel ingredients for cosmetic creams. A detailed environmental analysis was conducted for manufacturing cosmetic creams with these two ingredients. The study concentrated on the evaluation of the nanocomponents’ two raw materials, the consumption of power and water, which provided insight into the …

A total of 11 lecturers presented their research activities and …

Dear ladies and gentlemen, Zlatarna Celje d.o.o. invites you to the symposium “Presentation of gold nanoparticles synthesized in Zlatarna Celje d.o.o. and their possible use cases”, which will take place on March 8, 2024 at the Grand Plaza Hotel, Hall Safir at Slovenska cesta 60, 1000 Ljubljana starting at 12:00 p.m. Attached you can find …

Gold nanoparticles are an effective option for formulating inkjet-based conductive inks, for printing various patterns and creating sensing devices on affordable and biodegradable substrates, like commercial photo papers. Customizing gold nanoparticle ink formulations is still difficult since the ink needs to have certain physical, chemical, and rheological characteristics in order to have the right jettable …

Research findings show that gold nanoparticles have the potential to be used as coatings for protein-repellent materials in biomedical applications. Inhibiting unspecific blood protein adsorption is of crucial importance for blood-contacting implant devices, e.g. vascular grafts, stents, artificial joints, and others, as a preventive strategy for bacterial biofilm formation. The ability of polyvinylpyrrolidone (PVP)-stabilised gold …

We are participating in a project for Recycling of Rapid Antigen LFIA Tests (COVID-19) (acronym: LFIA-REC) together with partners: Faculty of Mechanical Engineering of the University of Maribor (project coordinator), UKC Maribor, IMT Ljubljana, FTPO Slovenj Gradec, Surovina d.o.o. Maribor, and Plastika Skaza d.o.o. The Covid-19 pandemic has resulted in huge amounts of waste from …

Implementing gold nanoparticles in optical coatings causes visible light absorption and scattering effects, which can be used for blocking Ultra-Violet light, eliminating blue light from display monitors, or for decoration. A study was published where gold nanoparticles have been incorporated into a coating along with C60 fullerene on a commercially established eyewear product. The used …

Lateral flow immunoassays (LFIAs) are simple diagnostic devices, used to detect targeted analytes – also called rapid antigen tests. There are many wasted and expired, unused rapid tests from the Covid-19 pandemic which may be recycled into new material components. The aim of this published study was to recover gold nanoparticles that are used as …

Gold nanoparticles are extremely interesting, because they have completely different electronic, optical, and thermal properties compared to their bulk counterparts. Depending on their size, their melting points are tens or hundreds of degrees lower than bulk gold. For the practical use of dried gold nanoparticles, it is necessary to know their melting point temperature, as …

Cosmetic products with gold nanoparticles display enhanced anti-aging, moisturizing, and regenerative effects, which are mostly based on their sizes, shapes, surface charges, and dose of application. The use of nanoparticles as cosmetic additives raises questions about their safety, for which information is often obtained by testing them independently of the cosmetic product. As their physicochemical …
