About Platinum-Coated Gold Nanorods

Platinum-coated gold nanorods are bimetallic core–shell nanostructures consisting of a gold nanorod core encased in a platinum shell. The platinum shell can be deposited as a complete coating, discrete nanoparticles, or even site-selectively on specific regions of the nanorod.Why Platinum?Platinum offers several unique advantages:Superior catalytic activity:Platinum is one of the most effective catalysts, enabling a wide range of chemical reactions. It is widely used in catalytic converters, fue

About Mesoporous Polydopamine Nanoparticles

Mesoporous polydopamine nanoparticles are nanoscale particles (typically 50–300 nm in diameter) composed of self-polymerized dopamine, featuring a highly ordered pore structure with pore diameters in the 2–50 nm range. This mesoporosity creates a high specific surface area and large pore volume, enabling efficient loading of therapeutic payloads.Key Properties of MPDA NPsPropertyDescriptionSizeTypically 50–300 nmPore sizeTunable 5–20 nmSurface area50–200 m²/gPhotothermal conversion efficiency~30
