Article Synopsis
- - Nanoparticle-sensitized photoporation shows promise for delivering biologics into cells efficiently, but safety and regulatory issues limit its clinical use due to the nanoparticles needing to be in direct contact with cells.
- - Researchers developed light-sensitive iron oxide nanoparticles in biocompatible nanofibres that can permeabilize cell membranes through photothermal effects, allowing delivery of important molecules like CRISPR-Cas9 and siRNA without harming the cells.
- - In vivo studies in mice revealed that this method led to tumor regression by effectively downregulating PD1 expression in treated T cells, indicating its potential for safer and more effective therapeutic applications in stem cell and T cell therapies.
Different approaches for the determination of the Sr/Sr isotope ratio of high-Rb glass are compared in this work to assess the suitability of minimally invasive approaches for applications on medieval stained glass (from the ancient Abbey of Stavelot in Belgium). It was found that pneumatic nebulization multicollector inductively coupled plasma-mass spectrometry (PN-MC-ICP-MS) after acid digestion and chromatographic isolation of the target analyte out of the sample matrix can still be seen as the preferred method for the high-precision isotopic analysis of Sr in glass with high Rb and rare-earth element (REE) concentrations. Alternatively, the use of laser ablation (LA) for sample introduction is a powerful technique for the direct analysis of solid samples.
