Autor: Xiyu Duan, Zhen Qiu, Zhongyao Liu, Michael J. Mandella, Bishnu P. Joshi, Kenn R. Oldham, Thomas D. Wang, Supang Khondee, Katsuo Kurabayashi

Publikováno v: Biomedical Optics Express

We demonstrate vertical cross-sectional (XZ-plane) images of near-infrared (NIR) fluorescence with a handheld dual axes confocal endomicroscope that reveals specific binding of a Cy5.5-labeled peptide to pre-malignant colonic mucosa. This view is per

In vivo layer-resolved characterization of oral dysplasia via nonlinear optical micro-spectroscopy

Autor: Vicente A. Resto, Gracie Vargas, Susan McCammon, Suimin Qiu, Kert Edward

Publikováno v: Biomedical Optics Express

Optical spectroscopy has proven to be a powerful technique for studying neoplastic transformation in epithelial tissue. Since specific intra-layer precancerous changes originate in the stratified layers of the oral mucosa, layer-resolved analysis wil

Measurement and correction of transverse chromatic offsets for multi-wavelength retinal microscopy in the living eye

Autor: Pavan Tiruveedhula, Wolf M. Harmening, Lawrence C. Sincich, Austin Roorda

Publikováno v: Biomedical Optics Express

A special challenge arises when pursuing multi-wavelength imaging of retinal tissue in vivo, because the eye’s optics must be used as the main focusing elements, and they introduce significant chromatic dispersion. Here we present an image-based me

A liquid optical phantom with tissue-like heterogeneities for confocal microscopy

Autor: Ye Chen, Danni Wang, Jonathan T. C. Liu

Publikováno v: Biomedical Optics Express

Phantoms play an important role in the development, standardization, and calibration of biomedical imaging devices in laboratory and clinical settings, serving as standards to assess the performance of such devices. Here we present the design of a li

Cell assay using a two-photon-excited europium chelate

Autor: Gregory W. Faris, Jeanne P. Haushalter, Kenneth T. Kotz, Xudong Xiao

Publikováno v: Biomedical Optics Express

We report application of two-photon excitation of europium chelates to immunolabeling of epidermal growth factor receptor (EGFR) cell surface proteins on A431 cancer cells. The europium chelates are excited with two photons of infrared light and emit

Multiphoton spectral microscopy for imaging and quantification of tissue glycation

Autor: Hsin Yuan Tan, Vladimir A. Hovhannisyan, Chen-Yuan Dong, Ara Ghazaryan, Jo Ya Tseng, Shean-Jen Chen, Yang-Fang Chen, Wen Lo

Publikováno v: Biomedical Optics Express

Tissue glycation from diabetes and aging can result in complications such as renal failure, blindness, nerve damage and vascular diseases. In this work, we applied multiphoton microscopy for imaging and characterizing the extent of tissue glycation.
