<P>Molecular beacons (MBs) have shown fascinating applications in many biological fields. However, exploration of cost-effective, sensitive, stable and efficient MB for in situ live cell- based assay has still room for improvement. In this regards, we have developed a novel MB which bears a spherical graphite nanoparticle (GN) as a fluorescent quencher. The GN resulted in the high quenching efficiency, and the presence of GN enhanced the biological stability and transfection of the MB into the cells, thereby enabling the real-time survivin mRNA detection and quantification in the MCF-7 breast cancer cells. These results demonstrated that the advancement of the proposed MB containing a GN nanoquencher can be used as a robust molecular probe for genetic analysis in the cells.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2012/aamick.2012.4.issue-12/am301976r/production/images/medium/am-2012-01976r_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/am301976r'>ACS Electronic Supporting Info</A></P>

Hydrodynamic cavitation and its application in water treatment combined with ozonation: A review
Bing Wang,Yunxian Liu,Huan Zhang,Wen Shi,Mingyang Xiong,Chunyang Gao,Mingcan Cui 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.114 No.-
Advanced oxidation processes (AOPs) such as cavitation and ozonation have been used as an alternativeand effective option for the treatment of wastewater with difficult to biodegrade compounds. In thisreview, the necessity and advantages of combining hydrodynamic cavitation with ozonation (HC/O3)were initially discussed. The discussion of the mechanism of the HC/O3 process revealed the presenceof both mechanical and chemical effects. Overviews of earlier work with HC/O3 technology were thensummarised to show the positive synergies and the HC devices in different wastewater treatments. Recommendations were given for parameter selection by analysing the impact of important operatingparameters on process performance. Energy efficiency and cost comparisons indicated that the HC/O3process was more cost effective than the individual process. Overall, the HC/O3 process with optimisedconditions is able to increase the degradation rate of refractory pollutants by more than 40% comparedto the HC process alone.
