Acid-induced and pH-controlled Reversible Switching of Broad-Spectrum Antibacterial Activity

February 13, 2018
Author(s)
Yin Y. Nelson, Vytautas Reipa, Xiaohong Wang, Kenneth Mineart, Vivek M. Prabhu, Nancy J. Lin, Jirun Sun
Bacterial resistance to antimicrobials is threatening millions of human lives due to indiscriminate overuse and environmental build-up of antibiotics. We present the smart regulation of antibacterial activity in biologically relevant conditions to reduce

Spatial Distribution of Hydrophobic Drugs in Model Nanogel-core Star Polymers

December 5, 2017
Author(s)
Vivek M. Prabhu, Guangmin Wei, Robert D. Miller, Victoria A. Piunova, William Swope, Amber Carr
Star polymers with a cross-linked nanogel-core are promising carriers of cargo for therapeutic applications due the synthetic control of amphiphilicity of arms and the stability to infinite dilution. Three nanogel-core star polymers were investigated to

Equilibrium Self-Assembly, Structure, and Dynamics of Clusters of Star-Like Micelles

October 17, 2015
Author(s)
Vivek M. Prabhu, Shrinivas Venkataraman, Yi Yan Yang, James Hedrick
Small-angle neutron scattering and static and dynamic light scattering have characterized the hierar-chical structure and dynamics of clusters of self-assembled star-like micelles formed by oligocarbonate-fluorene func-tionalized polyethylene glycol

Formation of Disk- and Stacked Disk-Like Self-Assembled Morphologies from Cholesterol Functionalized Aliphatic Polycarbonate Containing Amphiphilic Diblock Copolymers

June 10, 2013
Author(s)
Vivek M. Prabhu, Shrinivas Venkataraman, Ashlynn Lee, Yi Yan Yang, James Hedrick, Hareem Maune
In this study, a cholesterol functionalized aliphatic cyclic carbonate monomer, 2-(5-methyl-2-oxo-1,3-dioxane-5-carboxyloyloxy)ethyl carbamate (MTC-Chol) was synthesized. The organo-catalytic ring opening polymerization of MTC-Chol was accomplished by

Aggregation/agglomeration state of carbon nanotubes

October 12, 2012
Author(s)
Vivek M. Prabhu, Toshiya Okazaki, Takeshi Eitoku, Masayoshi Tange, Haruhisa Kato
Evaluation of aggregation and agglomeration of carbon nanotube (CNT) solution has been one of the key issues for applications. Here we introduce a simple method based on depolarized dynamic light scattering (DDLS) performed at multiple scattering angles to

Vertically Segregated Structure and Properties of small molecule-polymer blend semiconductors for organic thin film transistors

August 27, 2012
Author(s)
Nayool Shin, Dean DeLongchamp, Jihoon Kang, Regis J. Kline, Lee J. Richter, Vivek Prabhu, Balaji Purushothamanc, John E. Anthony, Do Y. Yoon
The phase-segregated structure and the electrical properties of thin film blends of the small-molecule semiconductor fluorinated 5,11-bis(triethylsilylethynyl) anthradithiophene with insulating binder polymers were studied for organic thin film transistor
