The rapid growth in nanomaterial applications have revealed limitations in available physicochemical characterization methods. An in situ electrochemical small-angle neutron scattering (eSANS) methodology was devised that enables direct measurements of nanomaterial dispersion structure while undergoing reduction-oxidation (redox) reactions at the vitreous carbon electrode. Furthermore, these po...

In the present communication we report the fabrication a unique core-shell inorganic nanomaterial with potential therapeutic and diagnostic functions. It contains an iron-cobalt (FeCo) core that demonstrates MRI contrast property and a thin nanoshell of gold that inhibits the function of a pro-angiogenic growth factor, VEGF165. Au(FeCo) core-shell nanomaterials are fabricated in the gas phase a...

A novel magneto-active gel based nanomaterial system is presented to provide precise control of temperature to a localized area in response to externally controlled magnetic stimuli. Integration of ferromagnetic nanoparticles (Fe3O4) in the polyethylene glycol (PEG) based thermo-responsive polymer provides the swelling and de-swelling behavior of magnetic stimuli controlled system by generating...

A facile method for the synthesis of metal nanostructure-decorated two-dimensional (2D) semiconductor nanosheets was developed. The solution-processable molybdenum trioxide (MoO3) nanosheet was used as a template for direct liquid-phase growth of platinum nanoparticles (Pt NPs) under ambient conditions. Results show that the Pt NPs with sizes of 1-3 nm were uniformly grown on the MoO3 surface. ...

Since their synthesizing introduction to the research community, nanomaterials have infiltrated almost every corner of science and engineering. Over the last decade, one such field has begun to look at using nanomaterials for beneficial applications in tissue engineering, specifically, cardiac tissue engineering. During a myocardial infarction, part of the cardiac muscle, or myocardium, is depr...

Antimicrobial action of nanomaterials is typically assigned to the nanomaterial composition, size and/or shape, whereas influence of complex corona stabilizing the nanoparticle surface is often neglected. We demonstrate sequential surface functionalization of tyrosine-reduced gold nanoparticles (AuNPs(Tyr)) with polyoxometalates (POMs) and lysine to explore controlled chemical functionality-dri...

In this paper, we present an innovative sensing nanomaterial for an interference localized surface plasmon resonance (iLSPR) sensor. The iLSPR is based on plasmonic gold nanoparticles with photonic thin-film multilayers of porous aluminum oxide (Al(2)O(3)) and aluminum (Al) on a substrate. With a controllable transparent Al(2)O(3) layer and a highly reflective Al layer, our new nanomaterial was...

Corresponding Author: Marcin Runowski, M.sc., e-mail: [email protected] Introduction to “nanoworld” nowadays, we live during an intensive development of science known as nanotechnology, which is closely related to chemistry of colloids. The average size of particles forming a given colloid is often in the range of 1–1000 nm (1 nm = 10-9 m). Due to the small size, such nanoparticles can form s...

Nanomaterial-based biosensors offer potential for rapid point-of-care testing or even real-time monitoring performed by the patient themselves to detect viral diseases. Through measuring diverse analyte levels, results can be transmitted wirelessly into a smartphone app. This review introduces latest works on nanomaterial-based detecting SARS-CoV-2, root cause of COVID-19 pandemic, summarizing ...
