In order to erase reactive oxygen species (ROS) related with the proliferation of tumor cells by reducing activity of hydrogen, we developed functional water containing nano-bubbles (diameters: <900 nm for 71%/population) hydrogen of 1.1-1.5 ppm (the theoretical maximum: 1.6 ppm) with a reducing ability (an oxidation-reduction potential -650 mV, normal water: +100-200 mV) using a microporous-fi...

Nano-structured crystalline tungsten(vi) oxides (WO(3)) were prepared using a colloidal crystal template method; these materials have increased specific surface area compared to crystalline WO(3) prepared without the template, and after platinum loading they show enhanced photocatalytic activity for acetic acid decomposition under visible light.

A novel single-pot method to exfoliate and functionalize acetylene black is proposed. The deliberate functionalization was found to enhance the intrinsic oxygen reduction efficiency along with the nucleation and growth of platinum nano-particles on the surface. The resulting material showed enormously high oxygen reduction reactivity compared to its commercial counterparts.

Simultaneous multi-element imaging using NanoSIMS (nano-scale secondary ion mass spectrometry), exploiting the novel combination of (195)Pt and (15)N in platinum-am(m)ine antitumour drugs, provides information on the internalisation and subcellular localisation of both metal and ligands, and allows identification of ligand exchange.

Poly(2,5 dimethoxyaniline) and Platinum (PDMA@ Pt) nanocomposite electrode was fabricated by the electrochemical method. PDMA@ Pt nano electrocatalyst size is around 150-200 nm. having electrocatalytic activity towards methanol oxidation reaction.

Background Resistance to platinum-based chemotherapy is a clinical challenge in the treatment of ovarian cancer (OC) and limits survival. Therefore, innovative drugs against platinum-resistance are urgently needed. Our therapeutic concept is based on the conjugation of two chemotherapeutic compounds to a monotherapeutic pro-drug, which is taken up by cancer cells and cleaved into active cytosta...

Platinum is the model catalyst in fuel cells because of its high activity toward oxygen reduction and hydrogen oxidation. However, applicability limited due to degradation under operating conditions. This process has been extensively studied by repeatedly oxidizing reducing electrode, which leads roughening surface nucleation growth platinum nano-islands. Although general picture this well know...

PURPOSE The objective of the present investigation was to evaluate the morphologic characteristics of self-assemblies of diamond (nano-D), silver (nano-Ag), gold (nano-Au), and platinum (nano-Pt) nanoparticles with Staphylococcus aureus (bacteria) and Candida albicans (fungi), to determine the possibility of constructing microorganism-nanoparticle vehicles. METHODS Hydrocolloids of individual...
