Journal ArticleDOI
Universal noble metal nanoparticle seeds realized through iterative reductive growth and oxidative dissolution reactions.
TL;DR: It is reported how iterative reductive growth and oxidative dissolution reactions can be used to systematically control seed structural uniformity and shown that iterative seed refinement leads to unprecedented noble metal nanoparticle uniformities and purities for eight different shapes produced from a single seed source.
Journal ArticleDOI
Building superlattices from individual nanoparticles via template-confined DNA-mediated assembly
Qing Yuan Lin,Jarad A. Mason,Zhongyang Li,Wenjie Zhou,Matthew N. O'Brien,Keith A. Brown,Matthew R. Jones,Serkan Butun,Byeongdu Lee,Vinayak P. Dravid,Koray Aydin,Chad A. Mirkin +11 more
TL;DR: DNA programmable assembly has been combined with top-down lithography to construct superlattices of discrete, reconfigurable nanoparticle architectures on a gold surface over large areas that provide a platform to systematically study and control light-matter interactions in nanoparticle-based optical materials.
Journal ArticleDOI
Human T cell lymphotropic virus type I Tax protein trans-activates interleukin 15 gene transcription through an NF-κB site
Nazli Azimi,Keith A. Brown,Richard N. Bamford,Yutaka Tagaya,Ulrich Siebenlist,Thomas A. Waldmann +5 more
TL;DR: Evidence for trans-activation of the IL-15 gene by the HTLV-I Tax protein through an NF-κB motif is presented and a potential role for IL- 15 in HTLV -I-associated diseases such as adult T cell leukemia andHTLV- I-associated myopathy/tropical spastic paraparesis is suggested.
Journal ArticleDOI
Strong Coupling between Plasmonic Gap Modes and Photonic Lattice Modes in DNA-Assembled Gold Nanocube Arrays
Qing Yuan Lin,Zhongyang Li,Keith A. Brown,Matthew N. O'Brien,Michael B. Ross,Yu Zhou,Serkan Butun,Peng-Cheng Chen,George C. Schatz,Vinayak P. Dravid,Koray Aydin,Chad A. Mirkin +11 more
TL;DR: It is shown that optical metasurfaces with such control can be constructed using an approach that combines top-down and bottom-up processes, wherein gold nanocubes are assembled into ordered arrays via DNA hybridization events onto a gold film decorated with DNA-binding regions defined using electron beam lithography.
Journal ArticleDOI
Nucleotide sequence of the leader region of the phenylalanine operon of Escherichia coli.
TL;DR: The pheA structural gene of the phenylalanine operon of Escherichia coli is preceded by a transcribed leader region of about 170 nucleotide pairs and the roles of synthesis of the Phe-rich leader peptide and secondary structure of the leader transcript in the regulation of transcription termination at the attenuator of the phe operon are discussed.
