Data for paper "A new mode of contrast in biological second harmonic generation microscopy"

<p>Enhanced image contrast in biological second harmonic imaging microscopy (SHIM) has previously been reported via quantitative assessments of forward- to epi-generated signal intensity ratio and by polarization analysis. Here we demonstrate a new form of contrast: the material-specific, wavelength-dependence of epi-generated second harmonic generation (SHG) excitation efficiency, and discriminate collagen and myosin by ratiometric epi-generated SHG images at 920 nm and 860 nm. </p> <p>Collagen shows increased SHG intensity at 920 nm, while little difference is detected between the two for myosin; allowing SHIM to characterize different SHG-generating components within a complex biological sample.</p><p><br></p><p>Scientific Reports 7(1) Article number:13331 (2017)</p> <p>DOI: 10.1038/s41598-017-13752-y</p>
