Recent advances in fiber optics, sources and detectors, imaging, and computer-controlled instrumentation have stimulated a period of unprecedented growth in the development of photonics technologies for a wide variety of diagnostic and therapeutic clinical applications. These include the application of quantitative optical spectroscopy and imaging for the detection of precancerous lesions in th...

The use of tapered optical fibers, i.e., optical nanofibers, for spectroscopy and the detection of small numbers of particles, such as neutral atoms or molecules, has been gaining interest in recent years. In this review, we briefly introduce the optical nanofiber, its fabrication, and optical mode propagation within. We discuss recent progress on the integration of optical nanofibers into lase...

in the surgical treatment of malignant tumors, it is crucial to characterize the tumor as precisely as possible. the determination of the exact tumor location as well as the analysis of its properties is very important in order to obtain an accurate diagnosis as early as possible. in neurosurgical applications, the optical, non-invasive and in situ techniques allow for the label-free analysis o...

The combination of optical trapping with Raman spectroscopy provides a powerful method for the study, characterization, and identification of biological micro-particles. In essence, optical trapping helps to overcome the limitation imposed by the relative inefficiency of the Raman scattering process. This allows Raman spectroscopy to be applied to individual biological particles in air and in l...

in this paper, an energetic coordination compound namely pentamminenitratocobalt(iii) nitrate, [co(nh3)5(no3)](no3)2, was used as a new precursor for the preparation of co3o4 nanoparticles. the results showed that the complex is easily decomposed into the co3o4 nanoparticles at low temperature (200 °c) without employing a surfactant or solvent and any complicated equipment. the product was char...
