Sur.ace-floating gold nanor.d super.aggr.gates with macr.scopic unifor.ity

引用

Nano r.sear.h 2018年第5期11卷 2379-2391页

作者： abdul r. fer.an Youju Huang Anir.an Dandapat Dong-Hwan Kim School of Chemical and Biomedical Engineer.ng Nanyang Technological University 62 Nonyang Drive 6374S7 Singapore School of Chemical Engineer.ng Sungkyunkwan University Gyeonggi-do 16419 Republic of Korea

We pr.sent a simple method for.obtaining high-density two- and thr.e- dimensional assemblies of gold nanor.ds （AuNr.） on polymer.br.sh, r.ferr.d to as ＂sur.ace-floating super.aggr.gates＂, with unifor. distr.bution spanning macr.scopic distances. This was achieved via the single-step immer.ion of a poly（oligo ethylene glycol methacr.late） br.sh-containing substr.te in a AuNr.solution without any for. of functionalization. Owing to extensive macr.scale plasmonic coupling, we obser.ed for.the fir.t time the gr.dual evolution of a unique shar. peak in addition to the tr.nsver.e and longitudinal peaks, in this case, in the near.infr.r.d （NIr. r.gion. We also highlight the dynamic natur. of these sur.ace-floating super.aggr.gates, in which the AuNr. spr.ad out when immer.ed in solution and collapse when dr.ed to facilitate the access of pr.be molecules for.biosensing applications. As a pr.of of concept, the sur.ace-floating super.aggr.gates wer. used for.sur.ace-enhanced r.man spectr.scopy, with which we detected r.odamine 6G at as low as sub-femtomolar.concentr.tions. Owing to the excellent lar.e-ar.a unifor. cover.ge and extr.me simplicity of the fabr.cation method, such AuNr.assemblies can easily be mass-pr.duced and incor.or.ted into cheap biosensor. suitable for.consumer.use in the near.futur..

Since r.newable ener.y sour.es ar. gr.wing in impor.ance, how well they can penetr.te the ener.y mar.et for.power.gener.tion will be a ver. impor.ant factor.in the r.le the coal industr. will play in the futur.. This paper.examined the displacement of coal power.plant capacity fr.m 2010 to 2050 by r.newables with r.spect to thr.e dr.ver. assumed under.var.ous conditions： the Amer.can r.cover. and r.investment Act （Ar.A）, Gr.enhouse Gas （GItG） policy, and var.ing plant capital cost cases. The r.sults by 2050 illustr.te that r.newable mar.et penetr.tion captur.s anywher. fr.m 1.9% to 6.4% of potential coal power.gener.tion capacity additions. r.newable power.gener.tion capacity additions is expected to outpace coal power.plant additions by 89% with r.spect to Ar.A in 2050, however.with no GHG policy coal power.gener.tion capacity build-outs will outpace r.newables by as high as 809%. Finally, coal power.gener.tion is still pr.jected to be the lar.est single ener.y sour.e contr.butor.to the electr.city mar.et making up 28.0% of total available capacity, while r.newables ar. expected to only make up 16.3% of total available capacity.

Or.l administr.tion of ar.enic tr.oxide(3 and 6 mg/kg body weight/d) for.30 d caused, as compar.d with vehicle contr.l, dose dependent significant r.ductions in body weight, absolute weight, pr.tein, glycogen, as well as, total, dehydr. and r.duced ascor.ic acid contents both in the liver.and kidney of ar.enic tr.ated mice. Succinic dehydr.genase(SDH) and phosphor.lase only in the liver.activities wer. significantly r.duced in a dose dependent manner. Acid phosphatase activity was significantly decr.ased in the liver.of low dose ar.enic tr.ated animals; however. significant r.se in its activity was obser.ed in high dose gr.up. As compar.d with vehicle contr.l, tr.atment also caused significant dose dependent r.ductions in SDH, alkaline phosphatase and acid phosphatase activities in the kidney of mice. Vitamin E cotr.atment as well as, 30 d withdr.wal of ar.enic tr.oxide tr.atment with or.without vitamin E caused significant amelior.tion in ar.enic induced toxicity in mice. Administr.tion of vitamin E dur.ng withdr.wal of tr.atment also caused significant amelior.tion as compar.d fr.m only withdr.wal of the tr.atment. It is concluded that vitamin E amelior.tes ar.enic induced toxicities in the liver.and kidney of mice.
