Atp Sensing

: Adenosine 5'-triphosphate (ATP) plays a significant role in biological processes and the ATP level is closely associated with many diseases. In order to detect ATP in live cells, tissues and body fluids with a high sensitivity and selectivity, researchers have developed various sensing strategies. Particularly, owing to distinct physicochemical properties of nanomaterials and high sensitivity of fluorescence, a great deal of efforts have been devoted to developing nanomaterials-based approaches for fluorescent ATP sensing in recent years. In this review, we focus on the current development of nanomaterial-based fluorescent ATP sensors and discuss the sensing mechanisms in detail. The advantages and disadvantages of ATP sensing using different kinds of nanomaterials, including carbon nanomaterials, metal nanoparticles, semiconductor quantum dots, metal-organic frameworks and up-conversion nanoparticles have been thoroughly compared and discussed. Finally, current challenges and future prospects in this field are given.

Propionicin PLG-1, a bacteriocin produced by Propionibacterium thoenii strain P127, was tested for characteristics that could determine its usefulness as a food preservative: long-term storage stability and effectiveness in a food model system. Partially purified propionicin PLG-1 samples, lyophilized and nonlyophilized, were stored at 25, 4, and −20°C. Bacteriocin activity increased by as much as 200% over the first 10 days of storage in nonlyophilized samples stored at 25 or 4°C. Activity then decreased gradually for samples stored at 25°C while samples stored at 4°C retained high activity through 14 weeks of storage. Nonlyophilized samples frozen at −20°C and lyophilized samples stored at all temperatures did not change significantly in activity through 25 weeks of storage. Propionicin was added at 100 and 1,000 arbitrary units (AU)/ml to lactobacilli MRS broth and to skim milk, each inoculated with 105 cells per ml of Lactobacillus delbrueckii ATCC 4797. Upon incubation at 37°C with 1,000 AU/ml, cell numbers were reduced by at least 4 log units within 2 h and no viable cells were detected after 96 h in either medium. With 100 AU/ml of propionicin, viable cells were reduced by 2 log units within 12 h at 37°C, but culture growth resumed after 24 h. At 15°C, no viable cells were detected after 48 h in the presence of 1,000 AU/ml of propionicin, while viable cell counts were gradually reduced to about 10 cells per ml by 168 h in the presence of 100 AU/ml of propionicin.

In the industrialization of gelcasting, storage of ceramic slurry has been one of the key problems that must be solved. Except for sedimentation of ceramics particle, solidification properties of slurries were also affected after long-term storage. In this article, some factors in the process of slurry were discussed, and corresponding solution methods were put forward.
