Title: | Coherent intensity fluctuation model for autocorrelation imaging spectroscopy with higher harmonic generating point scatterers - a comprehensive theoretical study | Authors: | SLENDERS, Eli VAN DE VEN, Martin HOOYBERGHS, Jef AMELOOT, Marcel |
Issue Date: | 2015 | Source: | PHYSICAL CHEMISTRY CHEMICAL PHYSICS, 17 (29), 18937-18943 | Abstract: | We present a general analytical model for the intensity fluctuation autocorrelation function for second and third harmonic generating point scatterers. Expressions are derived for a stationary laser beam and for scanning beam configurations for specific correlation methodologies. We discuss free translational diffusion in both three and two dimensions. At low particle concentrations, the expressions for fluorescence are retrieved, while at high particle concentrations a rescaling of the function parameters is required for a stationary illumination beam, provided that the phase shift per unit length of the beam equals zero. | Notes: | Ameloot, M (reprint author), Hasselt Univ, Biomed, Bldg C, B-3590 Diepenbeek, Belgium. marcel.ameloot@uhasselt.be | Keywords: | fluorescence correlation spectroscopy; laser-scanning microscope; nonlinear correlation spectroscopy; 2nd-harmonic generation; molecular aggregation; membrane dynamics; cells; nanocrystals; diffusion; time | Document URI: | http://hdl.handle.net/1942/18980 | ISSN: | 1463-9076 | e-ISSN: | 1463-9084 | DOI: | 10.1039/C5CP02567B | ISI #: | 000358207400008 | Rights: | This journal is © the Owner Societies 2015. | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2016 |
