Investigating Lyophilization of Lipid Nanocapsules with Fluorescence Correlation Spectroscopy

Investigating lyophilization of lipid nanocapsules with fluorescence correlation spectroscopy.

This paper describes characterization of lyophilized lipid nanocapsules loaded with Alexa 488 by fluorescence correlation spectroscopy (FCS). Fluorimetry analysis of nanocapsules containing self-quenching concentrations of 5- and 6-carboxyfluorescein was performed to establish a point of reference for FCS. FCS results complemented the results obtained by fluorimetry for a bulk nanocapsule solut...

Investigating the motility of Ecoli using Fluorescence Correlation spectroscopy

Microrheology with fluorescence correlation spectroscopy.

We show that fluorescence correlation spectroscopy (FCS) using a commercial spectrometer can be applied to passive microrheological (MR) experiments. The method probes the local rheological properties of materials on length scales of the focus dimension of the confocal microscope. For a feasibility study, we performed measurements on a high molecular weight poly(ethylene oxide)-water solution t...

Fluorescence correlation spectroscopy and fluorescence cross-correlation spectroscopy.

This article focuses on methods based on fluctuation correlation spectroscopy to determine the formation of protein complexes in living cells. We present the principles of the fluctuation method applied to cells. We discuss the novelty and the promises of this approach. The emphasis is in the discussion of the underlying statistical assumptions of the image correlation spectroscopy analysis rat...
