Leakage Radiation

Label-free, fast, and single nanoparticle detection is demanded for the in situ monitoring of nano-pollutants in the environment, which have potential toxic effects on human health. We present the label-free imaging of single nanoparticles by using total internal reflection (TIR)-based leakage radiation microscopy. We illustrate the imaging of both single polystyrene (PS) and Au nanospheres with diameters as low as 100 and 30 nm, respectively. As both far-field imaging and simulated near-field electric field intensity distribution at the interface showed the same characteristics, i.e., the localized enhancement and interference of TIR evanescent waves, we confirmed the leakage radiation, transforming the near-field distribution to far-field for fast imaging. The localized enhancement of single PS and Au nanospheres were compared. We also illustrate the TIR-based leakage radiation imaging of single polystyrene nanospheres with different incident polarizations. The TIR-based leakage radiation microscopy method is a competitive alternative for the fast, in situ, label-free imaging of nano-pollutants.

Major Emphasis

Over the past several years many developments have taken place in the field of molecular spectroscopy. For Raman spectroscopy many of the improvements have arisen from technological innovations that include diode-based lasers, holographic notch filters and charged coupled detectors. In contrast, a majority of the developments in infrared spectroscopy have been in the area of new sampling accessories. A major emphasis has been placed on attenuated total internal reflection (ATR) accessories. The devices are allowing infrared spectroscopy to be employed in process control environments and quality control laboratories where the method is not only robust but has the advantages of limited sample preparation and/or in situ analysis.In the realm of microspectroscopy, ATR accessories have the added advantages of providing better spatial resolution, equal to or higher S/N for equivalent sample size compared to transmission measurements and most importantly the ability to collect spectra of small samples without the adverse effect of diffraction. One accessory which was developed several years ago is known as the Split-Pea.
