It includes an introduction to the techniques and several applications. The focus has been on how to achieve high precision SERS measurements, both qualitatively and quantitatively. READ MORE

  5. 8. Raman Spectroscopy and Hyperspectral Analysis of Living Cells Exposed to Nanoparticles

    Author : Linnea Ahlinder; Lars Österlund; Ioan Notingher; Uppsala universitet; []
    Keywords : Raman spectroscopy; Hyperspectral analysis; Multivariate data analysis; Nanotoxicology; Graphene oxide; Iron oxide; Titanium dioxide; Cells;

    Abstract : Nanoparticles, i.e. particles with at least one dimension smaller than 100 nm, are present in large quantities in ambient air and can also be found in an increasing amount of consumer products. It is known that many nanomaterials have physicochemical properties that differ from physicochemical properties of the same material in bulk size. READ MORE
