    Raman Holography Has Implications for Live Cell, Tissue Interrogation

    Article obtained from Photonics RSS Feed.

    Researchers from the Institute of Photonic Sciences (ICFO) have successfully demonstrated holographic Raman microscopy. The technology is poised to support wide-ranging applications, from live cell and tissue interrogation to, potentially, anti-counterfeiting.

    Because spontaneous Raman scattering is more than 10 orders of magnitude weaker than fluorescence, the technique is rarely employed. However, Raman can be enhanced dramatically on metal surfaces or in metallic nanogaps to surpass fluorescence response; probes of nanometric surface-enhanced Raman scattering (SERS), therefore, are promising candidates for biological sensing applications, because they avoid molecular distortion despite their effectiveness depending on the size,…
