Homologous tumor‐targeting biomimetic nanozyme for synergistic NIR‐II photothermal and chemodynamic therapy

BMEMat, EarlyView.
Studies reveal that a biomimetic nanoplatform based on a cancer cell membrane‐camouflaged Au‐MnOx nanozyme (Au‐MnOx@CCM) can achieve synergistic antitumor therapy by combining NIR‐II mediated PTT with enhanced CDT, offering a promising strategy for precise and efficient tumor therapy. Abstract The therapeutic potential of nanozyme‐mediated chemodynamic

Portable X-ray Fluorescence Spectrometry for the analyses of Cultural Heritage

IOP Conference Series: Materials Science and Engineering, 2012
Field Portable Energy Dispersive X Ray Fluorescence (FP-EDXRF) is particularly useful to analyze works of art, mainly because of his noninvasive and multielemental capability. In many situations FP-EDXRF is the only non invasive technique that can be realistically used to gain some information about the chemical composition of precious and unique ...
