    1. Towards characterization of bacterial colonies and biofilms: an approach based on swept source optical coherence tomography

      Towards characterization of bacterial colonies and biofilms: an approach based on swept source optical coherence tomography

      The continuous development of microorganism colonies may lead to the development of biofilms. The ability to observe bacterial layers in real time using Optical Coherence Tomography (OCT) can be beneficial for cross-sectional growth studies of bacterial biofilms. A new mathematical model has been developed and utilized to calculate the backscattering optical properties of sample and estimate the necessary parameters. The spectroscopic based analytical method has been successfully demonstrated for characterization of different bacterial colonies and biofilms. The results were verified with conventional ‘Gram staining’ method. The proposed analytical method has potential to monitor realtime growth kinetics of bacteria. The quantities ...

    2. Investigation of Puccinia triticina contagion on wheat leaves using swept source optical coherence tomography

      Investigation of Puccinia triticina contagion on wheat leaves using swept source optical coherence tomography

      We present an investigation on applicability of swept-source optical coherence tomography (SSOCT) to examine the internal structures of plant leaves. This study helps to identify the growth and spread of the leaf rust disease in leaves of wheat plants, caused by Puccinia triticina . The epidermal cell layer and parenchyma cell layer of the acquired OCT images are correlated with the histological images to show distinctive leaf morphological boundaries. In the OCT images, the thickness of the parenchyma cell layer in healthy and infected samples are compared and analyzed. Accurate morphological and quantitative information are obtained with our developed system for ...

    3. Zinc oxide nanoparticles (ZnONPs) as contrast agent for imaging of animal tissue using swept source optical coherence tomography (SSOCT)

      Zinc oxide nanoparticles (ZnONPs) as contrast agent for imaging of animal tissue using swept source optical coherence tomography (SSOCT)

      We present applicability of ZnO nanoparticles (ZnONPs) as a potential contrast agent for Optical Coherence Tomography (OCT) imaging. A 1064 nm laser source was used in a swept source configuration capable of a scanning rate of 100 kHz (100,000 A-lines/s). Swept Source Optical Coherence Tomography (SSOCT) is a variation of OCT, offering greater scan rates, higher resolution and signal-to-noise ratios. To enhance the contrast of an OCT frame, ZnO nanoparticles were used as an exogeneous contrast agent, which were fabricated using zinc acetic acid derivation and oxalic acid via precipitation. The particles were characterized using UV–vis Spectroscopy ...
