چکیده
The polycondensation of amino acids can originate complex polymers that display fascinating structural and optical properties. Thermally induced amidation l-lysine allows forming a branched polymer without the support any catalyst. is completed at 240–250 °C; higher temperatures, acid degrades. obtained polylysine particles have been studied by transmission electron microscopy (TEM), nuclear magnetic resonance, infrared spectroscopy allow for investigating different steps synthesis. resulting structure characterized peculiar properties, e.g., excitation-dependent blue fluorescence good quantum efficiency. Hydrogen bonds interactions are considered responsible properties both monomer solutions high concentrations nanopolymers.

Blue protein with red fluorescence.
The walleye (Sander vitreus) is a golden yellow fish that inhabits the Northern American lakes. The recent sightings of the blue walleye and the correlation of its sighting to possible increased UV radiation have been proposed earlier. The underlying molecular basis of its adaptation to increased UV radiation is the presence of a protein (Sandercyanin)-ligand complex in the mucus of walleyes. D...

Miniemulsion polymerization is one of heterogeneous polymerization method that can be effectively used to synthesis of various novel organic-inorganic nanocomposite particles. This method can provide opportunity of good incorporation between the polymer and inorganic phases in the formed submicrometer-sized particles. In this article, we report preparation polystyrene/silica nanocomposite p...

In this study, a new type of temperature sensor device was developed. The circular electrode of the thermal sensitive sensor was modified with TMT and O2 plasma to enhance the conductivity by forming a thin SnOxCy layer on the electrode surface. The Nano-Au particles were subjected to O2 plasma pretreatment to form peroxide groups on the surface. The thermally sensitive sensor was made by mixin...
متن کاملAzatryptophans endow proteins with intrinsic blue fluorescence.
Our long-term goal is the in vivo expression of intrinsically colored proteins without the need for further posttranslational modification or chemical functionalization by externally added reagents. Biocompatible (Aza)Indoles (Inds)/(Aza)Tryptophans (Trp) as optical probes represent almost ideal isosteric substitutes for natural Trp in cellular proteins. To overcome the limits of the traditiona...
متن کاملBlue light-induced, intrinsic vacuolar fluorescence in onion guard cells.
Guard cells of onion irradiated with broad-band blue light display a green intrinsic fluorescence. The fluorescence has been found in eleven species of Allium, but it has not been observed in any other monocot or dicot examined. The fluorescence occurs only in guard cells and is absent in neighbouring epidermal cells. During development it is first apparent in guard mother cells soon after the ...
