In nature there are various specific reactions for which highly selective detection or support is required to preserve their bio-specificity or/and functionality. In this respect, mimics of cell membranes and bio-compartments are essential for developing tailored applications in therapeutic diagnostics. Being inspired by nature, we present here biomimetic nanocompartments with ion-selective mem...

an aqueous extract of pimpinella anisum was used for green synthesis of silver nanoparticles by bio reduction of an aqueous solution of silver nitrate. silver nanoparticles were characterized by uv–vis spectrometry, fourier transform infrared spectroscopy (ftir), x-ray diffraction (xrd) analysis, scanning electron microscopy (sem) and energy-dispersive x-ray analysis (edax). the increase in abs...

researchers have found a big interest in biological application of fourier transform infrared (ftir) spectroscopy. evaluating many diseases, staging them and studying the chemical structures of different formed compounds in diseases are some of the research applications of ftir. cancer is also one of these diseases. researchers are trying to set up ftir methods to detect and diagnose cancer cel...

Background: Developing effective methods for the synthesis of bio-compatible and non-toxic nanoparticles is the main goal of nanotechnology. In the most chemical methods, a chemical reducing agent is used to reduce metal ions. But, in chemical methods, the stability of nanoparticles is controversial and synthesis in large sizes is much more difficult. Moreover, there is an incr...

in present study we studied using green routes for microwave assisted synthesis of alumina nanoparticles from aluminum nitrate. it was revealed that when plant extracts are used, no specific stabilizer is needed. structural characterization of nanoparticles was studied using x-ray diffraction that showed semi-crystalline structure for two of plant extracts, other xrd patterns had no significant...

the aim of the present study was to assess the bio-trickling filter startup for the treatment ofwastewater produced by pegah dairy company at psychrophilic condition. the startup time of a bio-tricklingfilter is directly proportional to the concentration of microbial population. abio-trickling column with a height of150 cm was packed with lava rocks with the liquid recirculated through the pack...

BACKGROUND Escherichia coli is one of the best studied microorganisms and finds multiple applications especially as tool in the heterologous production of interesting proteins of other organisms. The heterologous expression of special surface (S-) layer proteins caused the formation of extremely long E. coli cells which leave transparent tubes when they divide into single E. coli cells. Such na...

The development of luminescent mercury sulfide quantum dots (HgS QDs) through the bio-mineralization process has remained unexplored. Herein, a simple, two-step route for the synthesis of HgS quantum dots in bovine serum albumin (BSA) is reported. The QDs are characterized by UV-vis spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, luminescence, Raman spectroscopy, transmission ele...

The study compared the net decline of intramyocellular lipids (IMCL) during exercise (n = 18) measured by biochemical assay (BIO) and Oil Red O (ORO) staining on biopsy samples from vastus lateralis muscle and by (1)H-MR spectroscopy (MRS) sampled in an 11 x 11 x 18-mm(3) voxel in the same muscle. IMCL was measured before and after a 2-h cycling bout ( approximately 75% V(.)(O(2) peak)). ORO an...
