Autofluorescence imaging of early colorectal cancer.

Journal of biophotonics

Takeuchi Y, Hanaoka N, Hanafusa M, Ishihara R, Higashino K, Iishi H, Uedo N.
PMID: 21557491
J Biophotonics. 2011 Aug;4(7):490-7. doi: 10.1002/jbio.201100013. Epub 2011 May 09.

Autofluorescence imaging (AFI) is expected to better detect colorectal neoplasms than the conventional white light imaging (WLI). The AFI image of colorectal cancer is different according to its macroscopic type. Protruded lesion, which is the most common macroscopic type...

On-tubing fluorescence measurements of the band broadening of contemporary injectors in ultra-high performance liquid chromatography.

J Chromatogr A. 2018 Feb 02;1535:44-54. doi: 10.1016/j.chroma.2017.12.032. Epub 2017 Dec 15.

We report on a detailed study of the injection contribution to band broadening in contemporary UHPLC-instruments, using either flow-through needle or fixed loop injection (full loop). Using on-tubing fluorescence measurements at the outlet of the injector valve, very localized...

[Application of novel quantum dot-based molecularly imprinted fluorescence sensor in rapid detection].

Se pu = Chinese journal of chromatography

Ma J, Lian Z, He C, Wang J, Yu R.
PMID: 34212579
Se Pu. 2021 Aug;39(8):775-780. doi: 10.3724/SP.J.1123.2021.02025.

A critical need in analytical chemistry is the efficient fabrication of selective and sensitive sensors to detect trace analytes in complicated samples. In recent years, fluorescence analysis has been widely used in environmental research and the life sciences due...

Fluorescence lifetime-activated droplet sorting in microfluidic chip systems.

Lab on a chip

Hasan S, Geissler D, Wink K, Hagen A, Heiland JJ, Belder D.
PMID: 30604804
Lab Chip. 2019 Jan 29;19(3):403-409. doi: 10.1039/c8lc01278d.

We present a highly efficient microfluidic fluorescence lifetime-activated droplet sorting (FLADS) approach as a novel technology for droplet manipulation in lab-on-a-chip devices. In a proof-of-concept study, we successfully applied the approach to sort droplets containing two different fluorescent compounds...

In micro-heterogeneous media (e.g. membranes, micelles and colloidal systems), the fluorescence decay in the absence of quencher is usually intrinsically complex, e.g. due to the existence of several sub-populations with different micro-environments. In this case it is impossible to...

Characterization of the fluorescence emission properties of prodan in different reverse micellar environments.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy

Sengupta B, Guharay J, Sengupta PK.
PMID: 10888447
Spectrochim Acta A Mol Biomol Spectrosc. 2000 Jun;56(7):1433-41. doi: 10.1016/s1386-1425(00)00245-6.

We have examined the steady state and time resolved fluorescence emission properties of the hydrophobic fluorescence probe, prodan, in three representative reverse micellar systems formed by the surfactants poly(oxyethylene) (tetramethylbutyl) phenylether (Triton X-100, neutral), cetyl trimethylammonium bromide (CTAB, cationic)...

Rapid Fluorescence-based Characterization of Single Extracellular Vesicles in Human Blood with Nanoparticle-tracking Analysis.

Journal of visualized experiments : JoVE

Weber A, Wehmeyer JC, Schmidt V, Lichtenberg A, Akhyari P.
PMID: 30663708
J Vis Exp. 2019 Jan 07;(143). doi: 10.3791/58731.

Extracellular vesicles (EVs), including exosomes, are specialized membranous nano-sized vesicles found in bodily fluids that are constitutively released from many cell types and play a pivotal role in regulating cell-cell communication and a diverse range of biological processes. Many...

Hybrid Structure White Organic Light Emitting Diode for Enhanced Efficiency by Varied Doping Rate.

Journal of nanoscience and nanotechnology

Kim DE, Kang MJ, Park GR, Kim NK, Lee BJ, Kwon YS, Shin HK.
PMID: 27455730
J Nanosci Nanotechnol. 2016 Mar;16(3):2900-3. doi: 10.1166/jnn.2016.11083.

Novel materials based on Zn(HPB)2 and Ir-complexes were synthesized as blue or red emitters, respectively. White organic light emitting diodes were fabricated using the Zn(HPB)2 as a blue emitting layer, Ir-complexes as a red emitting layer and Alq3 as...
