Pyrene fluorescence intensity and conductivity measurements were used to determine the cmc of two monomeric surfactants namely, dodecyltrimethylammonium bromide and cetyltrimethylammonium bromide as well as two gemini surfactants, 16-3-16 2Br and 16-4-16 2 ...

The aim of tissue engineering is to regenerate tissue for the purpose of repairing or replacing diseased or injured tissue. Therefore, cells that are able to proliferate are seeded on scaffolds that provide mechanical stability and direct the three-dimensi ...
A scanning electrochemical microscopy (SECM) protein detection methodology has been developed based on the tagging of free cysteines and other nucleophiles in proteins and peptides by benzoquinone. The tagged proteins are detected by the mediated reduction ...
The study of molecular dynamics at the single-molecule level with fluorescence correlation spectroscopy (FCS) and far-field optics has contributed greatly to the functional understanding of complex systems. Unfortunately, such studies are restricted to len ...

We report on a simple method for enhancing the efficiency of photoluminescence (PL) emission from selected chiral forms of semiconducting single-wall carbon nanotubes (SWCNTs). The method is based on the use of a fluorescent dye (Nile blue A) that shows th ...
We present steady-state and broadband femtosecond fluorescence spectra of the protonated Schiff base of retinal in various protic and aprotic solvents, as a function of the excitation wavelength. A detailed spectral decomposition of the time-resolved fluor ...
Infrared absorption spectroscopy enabling direct access to vibrational fingerprints of the molecular structure is a powerful method for functional studies of bio-molecules. Although the intrinsic absorption cross-sections of IR active modes of proteins are ...
This thesis introduces a collection of physics-based methods for super-resolution in optical microscopy. The core of these methods constitutes a framework for 3-D localization of single fluorescent molecules. Localization is formulated as a parameter estim ...
The distributions of organic additives in self-leveling flooring compounds (SLCs) were investigated using laser-scanning microscopy for the selective visualization of the additives, which had been previously stained by a fluorescent dye. The distributions ...
