Publication year: 2011
Authors: Xiaomeng Liu†, Arja-Helena Vesterinen§, Jan Genzer‡, Jukka V. Seppälä§, and Orlando J. Rojas*†∥
Published in: Langmuir, 2011, Vol. 27 (16), p. 9769–9780
We study the adsorption of a symmetric triblockcopolymer of ethylene oxide, EO, and propylene oxide, PO,end-capped with quarternized poly(2-dimethylaminoethylmethacrylate), DMAEMA (DMAEMA24EO132PO50EO132DMAEMA24). Light scattering and tensiometry are used tomeasure the relative size of the associated structures and surfaceexcess at the airliquid interface. [...]

Affinity Interaction between Hexamer Peptide Ligand HWRGWV and Immunoglobulin G Studied by Quartz Crystal Microbalance and Surface Plasmon Resonance

Publication year: 2010
Authors: Fei Sen; Under the direction of Dr. Ruben G. Carbonell
Published in: Ph.D Dissertation, 2010, Chemical Engineering
SHEN, FEI. Affinity Interaction between Hexamer Peptide Ligand HWRGWV and Immunoglobulin G Studied by Quartz Crystal Microbalance and Surface Plasmon Resonance. (Under the direction of Dr. Ruben G. Carbonell.) Immunoglobulins (Ig), also referred to as antibodies, act as protective agents against pathogens trying to invade an organism. Human immunoglobulin G (hIgG), as the most prominent immunoglobulin presented in serum and other human fluids, has broad applications in fields like immunotherapy and clinical diagnostics. [...]

Surface Plasmon Resonance on Nanoscale Organic Films

Publication year: 2010
Authors: Willem M. Albers and Inger Vikholm-Lundin
Published in: Nano-Bio-Sensing, 1st ed, Chapter 4, Springer 2010
Surface Plasmon Resonance (SPR) has evolved over the past 20 years into a very versatile detection method, particularly in biosci- ence applications. Not only the scientific literature [...]

Adsorption of a Nonionic Symmetric Triblock Copolymer on Surfaces with Different Hydrophobicity

Publication year: 2010
Authors: Xiaomeng Liu†, Dong Wu‡, Salomon Turgman-Cohen§, Jan Genzer§, Thomas W. Theyson∥ and Orlando J. Rojas*†⊥∥
Published in: Langmuir 2010, 26(12), 9565–9574
This study investigates the adsorption of a symmetric triblock nonionic polymer comprising ethylene oxide (EO) and propylene oxide (PO) blocks (Pluronic P-105, EO37PO56EO37) on a range of substrates including hydrophobic, i.e., polypropylene (PP), poly(ethylene terephthalate) (PET), nylon, and graphite, and hydrophilic, i.e., cellulose and silica.[...]

Measurement of phthalocyanine binding kinetics with surface plasmon resonance method

Publication year: 2010
Authors: M. Karjalainen, V. Chukharev, N.V. Tkachenko, J. Lekkala
Published in: Poster, presented at Annual Meeting of European Optical Society EOS. October 26 -29, 2010, Paris, France
Phthalocyanine molecules are potential candidates for the structural elements of optoelectronic devices such as organic solar cells and chemical sensors. The binding self-assembling monolayers of phthalocyanine molecules to a gold surface was studied using surface plasmon resonance (SPR) method. [...]

Surface plasmon resonance instrument as a refractometer for liquids and ultrathin films

Publication year: 2010
Authors: H.Liang a,b, H.Miranto b,c, N.Granqvist b,d, J.W. Sadowski c, T.Viitala b, B.Wang a, M.Yliperttula b
Published in: Sensors and Actuators B: Chemical 2010, 149(1), 212-220
A surface plasmon resonance (SPR) setup in Kretschmann configuration is being utilized as a refractometer for both liquids as well as ultrathin films. The SPR signal detection technology used is based on a goniometer approach providing a wide angular scan range which facilitates highly accurate liquid and gas phase measurements. [...]

Development of diagnostic SPR based biosensor for the detection of pharmaceutical compounds in saliva

Publication year: 2010
Authors: Susanna Sonny, Adama M. Sesay, Vesa Virtanen
Published in: Proc. SPIE 7376, Laser Applications in Life Sciences, 737605
The aim of the study is to develop diagnostic tests for the detection of pharmaceutical compounds in saliva. Oral fluid is increasingly being considered as an ideal sample matrix. It can be collected non-invasively and causes less stress to the person being tested. [...]

Surface plasmon resonance analysis for detecting non-structural protein 1 of dengue virus in Indonesia

Authors: Widoretno 1 2, Sjahrurachman A. 3, Dewi B.E. 4, Lischer K. 5 6, Pratami D.K. 7, Flamandita D. 5, Sahlan M. 5 6
Published in: Saudi Journal of Biological Sciences, 2020, Vol. 8, p.1931-1937
Dengue is an acute febrile disease caused by dengue virus (DENV) that is transmitted by Aedes sp., which causes serious health conditions in many countries. Non-structural protein 1 (NS1) is a co-factor for the RNA replication of this virus, which represents a new strategy for the identification of dengue. Prompt and accurate laboratory diagnosis of this infection is required to assist in patient triage and management, as well as prevent the spread of this infection.[...]
