Functionalization of nanochannels by radio-induced grafting polymerization on PET track-etched membranes

10-Jun-2013 | Author(s): S.L. Soto Espinoza , C.R. Arbeitman , M.C. Clochard , M. Grasselli, Radiation Physics and Chemistry, 2013

Publication date: Available online 5 June 2013 Source:Radiation Physics and Chemistry Author(s): S.L. Soto Espinoza , C.R. Arbeitman , M.C. Clochard , M. Grasselli The application of swift-heavy ion bombardment to polymers is a well-established technique to manufacture micro- and ...


Hydrogen-Bonding-Induced Chain Folding and Vesicular Assembly of an Amphiphilic Polyurethane

22-May-2013 | Tathagata Mondal; Krishna Dan; Jolly Deb; Siddhartha S. Jana; Suhrit Ghosh, Langmuir, 2013

We have reported synthesis and vesicular assembly of a novel amphiphilic polyurethane with hydrophobic backbone and hydrophilic pendant carboxylic acid groups which were periodically grafted to the backbone via a tertiary amine group. In aqueous medium the polymer chain adopted a folded ...


Molecules, Vol. 18, Pages 5749-5760: Synthesis and Characterization of Oil-Chitosan Composite Spheres

16-May-2013 | Huang, Keng-Shiang ; Wang, Chih-Yu ; Yang, Chih-Hui ; Grumezescu, Alexandru Mihai; Lin, Yung-Sheng ; Kung, Chao-Pin ..., Molecules, 2013

Oil-chitosan composite spheres were synthesized by encapsulation of sunflower seed oil in chitosan droplets, dropping into NaOH solution and in situ solidification. Hydrophilic materials (i.e., iron oxide nanoparticles) and lipophilic materials (i.e., rhodamine B or epirubicin) could be ...


Permanent Fixing or Reversible Trapping and Release of DNA Micropatterns on a Gold Nanostructure Using Continuous-Wave or Femtosecond-Pulsed Near-Infrared Laser Light

23-Apr-2013 | Tatsuya Shoji; Junki Saitoh; Noboru Kitamura; Fumika Nagasawa; Kei Murakoshi; Hiroaki Yamauchi; Syoji Ito; Hiroshi M ..., Journal of the American Chemical Society, 2013

The use of localized surface plasmons (LSPs) for highly sensitive biosensors has already been investigated, and they are currently being applied for the optical manipulation of small nanoparticles. The objective of this work was the optical trapping of λ-DNA on a metallic nanostructure with ...


IJMS, Vol. 14, Pages 7391-7404: Fabrication of Magnetic-Antimicrobial-Fluorescent Multifunctional Hybrid Microspheres and Their Properties

02-Apr-2013 | Xiao, Ling-Han ; Wang, Tao ; Zhao, Tian-Yi ; Zheng, Xin ; Sun, Li-Ying ; Li, Ping ; Liu, Feng-Qi ; Gao, Ge ; Dong, A ..., International Journal of Molecular Sciences, 2013

Novel magnetic-antimicrobial-fluorescent multifunctional hybrid microspheres with well-defined nanostructure were synthesized by the aid of a poly(glycidyl methacrylate) (PGMA) template. The hybrid microspheres were fully characterized by scanning electron microscopy (SEM), transmission electron ...


Tension Sensing Nanoparticles for Mechano-Imaging at the Living/Nonliving Interface

26-Mar-2013 | Yang Liu; Kevin Yehl; Yoshie Narui; Khalid Salaita, Journal of the American Chemical Society, 2013

Studying chemomechanical coupling at interfaces is important for fields ranging from lubrication and tribology to microfluidics and cell biology. Several polymeric macro- and microscopic systems and cantilevers have been developed to image forces at interfaces, but few materials are amenable for ...


A reversible fluorescent chemosensor for cyanide in 100% aqueous solution

18-Mar-2013 | Sensors and Actuators B: Chemical, 2013

May 2013 Publication year: 2013Source:Sensors and Actuators B: Chemical, Volume 181 A new fluorescent chemosensor, sodium 2-(2-(1H-benzo[d]imidazol-2-yl)quinolin-8-yloxy)acetate (HL), based on 8-hydroxyquinoline derivative has been designed, synthesized and characterized. Once ...


Synthesis of highly monodisperse quantum dot‐loaded polymer beads by impregnation and precipitation techniques

22-Feb-2013 | Jiean Chen, Chengli Yang, Xue Li, Heng Zhang, Biwang Jiang, Journal of Polymer Science Part A: Polymer Chemistry, 2013

Abstract A novel approach to the synthesis of highly monodisperse quantum dot‐loaded polymer beads by combining impregnation and precipitation techniques was reported. The monodisperse poly(glycidyl methacrylate) (PGMA) beads were first synthesized by dispersion polymerization. Then, the PGMA ...


NIR- and FRET-Based Sensing of Cu2+ and S2- in Physiological Conditions and in Live Cells

09-Jan-2013 | Chirantan Kar; Manab Deb Adhikari; Aiyagari Ramesh; Gopal Das, Inorganic Chemistry, 2013

We have synthesized a new indole functionalized rhodamine derivative L1 which specifically binds to Cu2+ in the presence of large excess of other competing ions with visually observable changes in their electronic and fluorescence spectral behavior. These spectral changes are significant enough ...


One-Step Sensitive Detection of Salmonella typhimurium by Coupling Magnetic Capture and Fluorescence Identification with Functional Nanospheres

04-Jan-2013 | Cong-Ying Wen; Jun Hu; Zhi-Ling Zhang; Zhi-Quan Tian; Guo-Ping Ou; Ya-Long Liao; Yong Li; Min Xie; Zi-Yong Sun; Dai- ..., Analytical Chemistry, 2013

Sensitive, rapid, and reliable detection of bacteria has always been pursued due to the great threat of the bacteria to human health. In this study, a convenient one-step strategy for detecting Salmonella typhimurium was developed. Immunomagnetic nanospheres (IMNS) and immunofluorescent ...
