Descrizione generale
Platinum (Pt) is a highly ductile, malleable and unreactive metal. It is resistant to corrosion and stable at high temperatures. Although resistant to hydrochloric and nitric acid, it dissolves readily in hot aqua regia to form chloroplatinic acid.
Applicazioni
Platinum wire finds major applications as an electrode, such as:
- Auxiliary electrode in flow cell to determine ammonia content.
- Electrodes for photoconductive stimulation of neurons cultured on silicon wafers.
- Electrode to give current flow in electrophoresis chamber for ion migration.
- As a microelectrode-indicator electrode in voltammetry.
- As a transvascular embolic agent.
- To study chronopotentiometry of hydrogen peroxide with a platinum wire electrode or
- In gas detection instruments.

A sensor for the amperometric detection of aqueous ammonia was fabricated using the inkjet printing of dodecylbenzene sulfonate (DBSA)-doped polyaniline nanoparticles (nanoPANI) onto a screen-printed carbon paste electrode. The combination of the environmentally inert, aqueous nanoparticle dispersion with the inkjet

We recently reported that peritumoral CpG-ODN treatment, activating TLR-9 expressing cells in tumor microenvironment, induces modulation of genes involved in DNA repair and sensitizes cancer cells to DNA-damaging cisplatin treatment. Here, we investigated whether this treatment induces modulation of miRNAs
