Asymmetric and symmetric PCR of gold nanoparticles: A pathway to scaled-up self-assembly with tunable chirality
DOI: 10.1039/C2JM15800K, PaperYuan Zhao, Liguang Xu, Hua Kuang, Libing Wang, Chuanlai Xu
In this work we used a polymerase chain reaction (PCR) to produce complex superstructures from heterogeneously-sized gold nanoparticles. By controlling the number of PCR cycles and primer density, two distinct superstructures were assembled at asymmetric and symmetric PCR.

A novel approach to electrospinning of pristine and aligned MEH-PPV using binary solvents
DOI: 10.1039/C2JM15970H, PaperWei Zhong, Fan Li, Lie Chen, Yiwang Chen, Yen Wei
Continuous electrospinning of pristine and aligned MEH-PPV in binary solvents without adding a polymer or a surfactant has been demonstrated. Polarization anisotropy spectra of aligned electrospun fibers indicated preferential alignment of MEH-PPV along the electrospun fiber axis. Electrospun fibers of MEH-PPV/PCL had higher polarization anisotropy than aligned pristine MEH-PPV at emission peak.
