producing a mixture of the sample, the calibration solution, and Raman-scattering nanoparticles;
illuminating the mixture with an electric field to produce Raman-spectra of the analyte and the isotopic calibration standard simultaneously; and,
performing a ratiometric analysis of the Raman-spectra of the anlayte and the isotopic calibration standard to quantify the analyte,
wherein the analyte is selenate and the isotopic calibration standard is a sulfate isotope or a selenate isotope.

NON-LINEAR STRUCTURED ILLUMINATION MICROSCOPY

Howard Hughes Medical Ins...

1. A method comprising:(a) providing spatially-patterned activation radiation to a sample that includes phototransformable optical labels (“PTOLs”), wherein an optical parameter of the spatially-patterned activation radiation varies periodically in space within the sample;
(b) providing spatially-patterned excitation radiation to the sample, wherein an optical parameter of the spatially-patterned excitation radiation varies periodically in space within the sample,
wherein (a) and (b) create a non-linear fluorescence emission pattern within the sample, the pattern including H modulation harmonics, with H>1;
(c) detecting radiation emitted from the activated and excited PTOLs within the sample;
(d) storing detected radiation data for generating an image of the sample based on the detected radiation;
(e) spatially shifting one or both of the spatially-patterned excitation radiation and the spatially-patterned activation radiation with respect to the sample to spatially shift the non-linear fluorescence emission pattern within the sample;
(f) repeating (a)-(e) at least N times, with N>2; and
(g) generating a sub-diffraction-limited final image of the sample based on the stored data for the N positions of the non-linear fluorescence emission pattern within the sample.
