Computer colour matching with fluorescent dyes : The influence of fluorescence on reflectance - concentration relationships for fluorescent dyes, singly and in mixtures, and the effects on the prediction of recipes for use in colour matching.
… method of computer colour matching involving fluorescent dyes was developed. An ordinary abridged-spectroreflectometer with polychomatic illumination and a simulated D65 xenon light source was employed for all measurements. In addition to the normal K/S constants for non-fluorescent dyes and …

Spectrally Resolved Detector Arrays for Multiplexed Biomedical Fluorescence Imaging
The ability to resolve multiple fluorescent emissions from different biological targets in video rate applications, such as endoscopy and intraoperative imaging, has traditionally been limited by the use of filter-based imaging systems. Hyper and multispectral imaging facilitate the detection of …

Small Molecules Binding to Serpins
… Two systems were closely monitored during fluorescent binding studies, the ACT-CHY along with the AT:TRY interaction. Four different conformational variants of each system were studied including the native, cleaved, latent and complex forms. Three different fluorescent dyes were used to …

Chemical Nanolithography and Single Molecule Optical Imaging With Metal -Coated Probes
… groups. These written features, labeled with fluorescent dyes, biomolecules, and nanoparticles, were imaged with confocal microscopy and atomic force microscopy. The use of metal-coated AFM tips in apertureless near-field scanning optical microscopy of single molecules is also briefly …

Towards the Understanding of Fluorescence Quenching Mechanisms : Molecular Dynamics Simulations of Dye-Quencher Interactions in Biomolecular Systems
… The present thesis is a simulative study of two fluorescent dyes (rhodamine 6G and MR121) used in the development of fluorescence-based immunoassays for the detection of p53 antibodies. The "selective" fluorescence quenching property of tryptophan residues present in dye-conjugated peptide chains …

Design and Use of Fluorescent Assays to Study Plasminogen Activator and Other Serine Proteases Involved in Biological Control
… assays need to be devised. Because the xanthene dyes rhodamine and fluorescein are among the most fluorescent compounds known and, as such, can be detected at very low concentrations, derivatives of these fluorescent dyes were designed as fluorogenic substrates for the amidase and esterase …

The Total Synthesis and Cytoprotective Abilities of Dykellic Acid and Its Structural Analogs
… ROS quenching or caspase inhibition. Using fluorescent dyes sensitive to ROS it was established that dykellic acid is not capable of directly quenching ROS. Dykellic acid was also found to not directly inhibit caspase enzymes, an important family of enzymes in cellular death. While the …

THE CONSTRUCTION OF NAPHTHOTUBES AND THEIR APPLICATIONS IN MOLECULAR RECOGNITION, ENANTIOSELECTIVE RECOGNITION AND CHARGE TRANSFER
… abilities of amide naphthotubes with a series of fluorescent dyes were systematically discussed. Secondly, a new pair of water-soluble chiral naphthotubes with enantioselective recognition ability were synthesized and their chiral recognition abilities were thoroughly studied. Lastly, two new …

Ultraviolet Light and Fluorescence in Medicine: Their Application to the Problem of Microscopic Localization of Tetracycline
… into the general subject of ultraviolet light, fluorescent dyes, and interpretation, whose vastness is exceeded only by the inaccessibility of much of the basic work which has been printed in German journals and is not generally, if at all, available in this country. | Fluorescence is a physical …

Single stranded DNA: A new model system for single molecule polymer dynamics
… research for many years. For nearly two decades, fluorescently-labeled double stranded DNA (dsDNA) has been the model system for studying single molecule polymer dynamics in non-equilibrium conditions. However, dsDNA is a semiflexible polymer with markedly different local molecular properties …

Preparation and Characterization of Spray Dried Fluorescent Micro particles for Controlled Release in the Lungs.
The purpose of the thesis was to prepare fluorescent micro particles by spray drying technique for the purpose of imaging in lungs. The four formulations were prepared using two polymers, hydroxy propyl cellulose and chitosan and two fluorescent dyes, Rhodamine B and Evans blue. The four …

In vitro evaluation of cytotoxicity and cellular uptake of alternating copolymers for use as drug delivery vehicles
… targeting), perfluorocarbons (19F MR imaging), fluorescent dyes (NIRF imaging), and radioiodine (nuclear imaging and radioimmunotherapy) to the backbone. Attachment of hydrocarbon or perfluorocarbon sidechains provides amphiphilicity to produce the multimodal self-assembling micelles. …

Synthesis and applications of core functional hyperbranched polyglycerol
… materials and increasing the photostability of fluorescent dyes. The first chapter describes two methods for the synthesis of the polymers and its formal [3+2] cycloaddition with organic azides in the presence of copper, commonly referred to as click chemistry. The two methods allow preparation …

STED-4Pi Microscopy
… that is confirmed in experiments with ultrathin fluorescent layers. These results are so far considered to have the highest axial resolution for a light microscope. First biological images are recorded with membrane labeled bacteria at 40-50 nm resolution. A major issue is the photostability of …

Analysis of Flow and Transport in Refractive Index Matched Porous Media
… of particularly applicative solids, liquids and fluorescent dyes and the application of a method for the highly precise matching of refractive indices, the dynamics of the dye distribution inside a threedimensional porous medium could be determined with a high temporal and spatial resolution …

Polymers, Nanoparticles and Phospholipids
… than ∼2% with a longevity of 4∼5 days. Fluorescent dyes are encapsulated within the particle-stabilized liposomes, without leakage. Although these particle-stabilized liposomes are stable against fusion, ∼75% of the outer liposome surface remains unoccupied, which is still …

Development of quantitative methods for quality assessment of islets of Langerhans
… is based on a live/dead staining test with two fluorescent dyes, fluorescein diacetate (FDA) and propidium iodide (PI). These methods are operator- dependent and prone to error due to the variability in islet size and shape and are not predictive of transplantation outcome. We developed …

Mixed infections of maize dwarf mosaic virus and cucumber mosaic virus in maize
… protoplasts liposomes were produced. Initially fluorescent dyes were incorporated in them. These were fused to the maize protoplasts. Attempts were made to encapsulate virus particles in the liposomes and fuse them to maize protoplasts but this was not successful.
