Optical Properties of Luminescent Materials
(2015-09-14)
Summary: Sol-gel methods (SGMs) are nowadays well established and developed giving birth to a wonderful collection of new multifunctional materials only possible to be obtained due to the intrinsic flexibility and low ...
Polymethine cyanine dyes in beta-cyclodextrin solution: multiple equilibria and chemical oxidation
(JOHN WILEY & SONS LTD, 2010)
Absorption and fluorescence spectroscopy, electrochemical techniques, and semiempirical calculations were employed to characterize the multiple complexation equilibria between two polymethine cyanine dyes (IR-786 and ...
Cyanine dyes in solid state organic heterojunction solar cells
(2014-01-01)
Today numerous cyanine dyes that are soluble in organic solvents are available, driven by more than a century of research and development of the photographic industry. Several properties specific to cyanine dyes suggest ...
Predictive Model for Delivery Efficiency: Erythrocyte Membrane-Camouflaged Magnetofluorescent Nanocarriers Study
(2020-03-02)
Delivery efficiencies of theranostic nanoparticles (NPs) based on passive tumor targeting strongly depend either on their blood circulation time or on appropriate modulations of the tumor microenvironment. Therefore, ...
Single bead near-infrared random laser based on silica-gel infiltrated with Rhodamine 640
(2018-04-07)
Photoluminescence properties of single bead silica-gel (SG) embedded with a laser-dye were studied aiming at the operation of near-infrared (NIR) Random Lasers (RLs). The operation of RLs in the NIR spectral region is ...
A Highly Sensitive Fluorogenic Probe for Imaging Glycoproteins and Mucine Activity in Live Cells in the Near-Infrared Region
(Wiley VCH Verlag, 2018-04)
A novel fluorescent molecular probe is reported, which is able to detect glycoproteins, especially mucins, with high sensitivity and with a turn-on response along with a large Stokes shift (>130 nm), within the biologically ...
A systematic study on fluorescence contrast in near infrared diffuse transmittance imaging with indocyanine green
(N I R Publications, 2019-06-25)
Near infrared fluorescence imaging is a sensitive, noninvasive technique for diagnostic applications in biomedical optics. The main purpose of this work is thus to explore how to improve the contrast of images obtained by ...
Near–infrared photodynamic inactivation of S. pneumoniae and its interaction with RAW 264.7 macrophages
(2018-01-01)
Pneumonia is the main cause of children mortality worldwide, and its major treatment obstacle stems from the microorganisms increasing development of resistance to several antibiotics. Photodynamic therapy has been presenting, ...
Enhanced NIR-I emission from water-dispersible NIR-II dye-sensitized core/active shell upconverting nanoparticles
(2018-01-01)
Recently, there has been a surge in research studies directed towards near-infrared (NIR) dye-sensitized upconverting nanoparticles (UCNPs) as they carry the prominent advantages of a broader absorption range and enhanced ...
Photoinduced hole-transfer in semiconducting polymer/low-bandgap cyanine dye blends: evidence for unit charge separation quantum yield
(Royal Soc Chemistry, 2009-01-01)
Power-conversion efficiencies of organic heterojunction solar cells can be increased by using semiconducting donor-acceptor materials with complementary absorption spectra extending to the near-infrared region. Here, we ...
