Laser treatment of hemangiomas using spectroscopic feedback : the "smart scalpel"
… or PWS). Current PWS phototherapy relies on selective absorption of optical radiation by the ectactic blood vessels in a PWS resulting in thermally mediated vessel necrosis. Although shown to be effective, heating of the surrounding tissue by photon absorption results in unacceptable …

Diffraction spectroscopy of metalloproteins
X-ray absorption is not only element specific, but atom specific: two atoms of the same element in different states or in different neighbourhoods will have slightly different absorption characteristics. These energy dependent atomic form factors are carried over to the diffraction intensities. The …

The interplay between order and disorder in cholesteric hydroxypropyl cellulose films
… pigments and dyes, where colour is achieved by selective absorption. The formation of a cholesteric liquid crystalline phase is one route to achieve such structuring on the nanoscale. An especially promising candidate is hydroxypropyl cellulose (HPC), a bio-sourced, bio-compatible and …

An Investigation into the Use of a Plant-Expressed Virus-Like Particle as an Oral Vaccine Candidate
… intestine, intact VLPs should be available for absorption by the Follicle-associated epithelium (FAE), considered the main portal of entry for antigens in the gut. In this work, Hepatitis B core antigen (HBcAg) VLPs, expressed transiently in Nicotiana benthamiana leaves, were extracted, purified …

The confined self-assembly of photonic pigments: from synthetic polymer brushes to sustainable cellulosic colloids
… on chemical composition to produce colours by selective absorption and emission, it is also possible to create bright and vivid colours using nanostructured materials. Such structurally coloured materials are readily found in nature, from insects to plants, yet they are challenging to fabricate …

The unsteady combustion of radiant heat flux-driven energetic solids
… illustrate the importance of including in-depth absorption for typical wavelength-material combinations. The laser-recoil experimental technique has been further developed and demonstrated. Unsteady burning measurements of fine oxidizer composite (APF series) and a catalyzed double base (N5) …

Transport of Liquid Phase Organic Solutes in Liquid Crystalline Membranes
… due to increased sorption selectivity. Shape selective absorption of rod-like para-isomers in the nematic phase was observed in both 8CB and PCH5 LCs. A nonchiral based HPLC-CD (High Performance Liquid Chromatography-CD) system was developed for the characterization of enantioselective …

Synthesis and Characterization of Functional Mesostructures Using Colloidal Crystal Templating
… enabling novel mesostructures that exhibit selective absorption and emission. By using colloidal crystal templating, tunable photonic mesostructures were synthesized and characterized. With direct observation of the mesostructure evolution through fluorescence microscopy and computational …

A study of the influence of sperm surface proteins on the activity of avian spermatozoa In-vitro and In-vivo
… plasma and sperm surface-associated proteins, selective loss of proteins from the sperm surface, as well as secretion of some seminal plasma proteins and selective absorption of others by epithelial cells lining the excurrent ducts, continues in the ductus deferens and …

Reststrahlen band optics for the advancement of far-infrared optical architecture
… developing far-infrared emission sources using selective thermal emitters, which could operate more efficiently than their simple blackbody counterparts commonly used as sources in this wavelength region. The later projects probe the possible means of linking bulk optical phonon populations …

Preparation of nanovehicles for targeted drug delivery
… for efficient and targeted delivery of drugs for selective and enhanced absorption. This work throws light on the preparation of biodegradable and non-toxic nanoparticulate systems for targeted drug delivery. The drug vehicles were made by two different processes namely electrostatic interactions …
