Here, a detailed protocol for the differentiation of hiPSCs into neurons and glia is described. Chemistry A Novel Technique for Raman Analysis of Highly Radioactive Samples Using Any Standard Micro-Raman Spectrometer Jean-Yves Colle1, Mohamed Naji1, Mark Sierig1, Dario Manara1 1European Commission, Joint Research Centre (JRC) We present a technique for Raman spectroscopic analysis of highly radioactive samples compatible with any standard micro-Raman spectrometer, without any radioactive contamination of the instrument. We also show some applications using actinide compounds and irradiated fuel materials.
