Temperature-Induced Denaturation of BSA Protein Molecules for Improved Surface Passivation Coatings

16 Oct 2018

Bovine serum albumin (BSA) is the most widely used protein for surface passivation applications, although it has relatively weak, non-sticky interactions with hydrophilic surfaces such as silica-based materials. Herein, we… Read more

Nanoplasmonic sensing and capillary electrophoresis for fast screening of interactions between phosphatidylcholine biomembranes and surfactants

16 Oct 2018

Nanoplasmonic sensing (NPS), based on localized surface plasmon resonance, with sensors composed of glass covered with golden nanodisks and overlaid with a SiO2 coating was applied in this study. Egg… Read more

Quantitative Comparison of Protein Adsorption and Conformational Changes on Dielectric-Coated Nanoplasmonic Sensing Arrays

16 Oct 2018

Nanoplasmonic sensors are a popular, surface-sensitive measurement tool to investigate biomacromolecular interactions at solid-liquid interfaces, opening the door to a wide range of applications. In addition to high surface sensitivity,… Read more

Thermal properties and segmental dynamics of polymer melt chains adsorbed on solid surfaces

16 Oct 2018

The glass transition of supported polystyrene (PS) and poly(2-vinylpyridine) (P2VP) thin films in the vicinity of the substrate interface was studied by using a nanoplasmonic sensing (NPS) method. This “nanocalorimetric”… Read more

Thermal cis-to-trans Isomerization of Azobenzene Side Groups in Metal-Organic Frameworks investigated by Localized Surface Plasmon Resonance Spectroscopy

16 Oct 2018

The energy barrier for cis-to-trans isomerization is among the key parameters for photoswitchable molecules such as azobenzene. Recently, we introduced a well-defined model system based on thin films… Read more

Preferential oxidation of CO in H2 on Cu and Cu/CeOx catalysts studied by in situ UV–Vis and mass spectrometry and DFT

16 Oct 2018

Preferential oxidation of CO in H2 was studied by in situ ultraviolet–visible (UV–Vis) and mass spectrometry on flat model Cu and Cu/CeOx catalysts. The experimental findings were interpreted and compared with… Read more

Multi-Component Uptake of Dye Molecules by Films of Nanoporous Metal–Organic Frameworks

16 Oct 2018

Nanoporous materials, such as metal–organic frameworks (MOFs), enable the separation of various molecular mixtures. Thus, detailed knowledge of multi-component diffusion properties of the guest molecules in the pores is vital. Read more

Indirect Nanoplasmonic Sensing Platform for Monitoring Temperature-Dependent Protein Adsorption

16 Oct 2018

The development of highly surface-sensitive measurement approaches to monitor protein adsorption across different temperatures would advance understanding of how thermally activated processes contribute to the denaturation of adsorbed proteins. Herein,… Read more

Cholesterol affects the interaction between an ionic liquid and phospholipid vesicles. A study by differential scanning calorimetry and nanoplasmonic sensing

16 Oct 2018

The present work aims at studying the interactions between cholesterol-rich phosphatidylcholine-based lipid vesicles and trioctylmethylphosphonium acetate ([P8881][OAc]), a biomass dissolving ionic liquid (IL). The effect of cholesterol was assayed… Read more

Gold nanoparticle-based localized surface plasmon immunosensor for staphylococcal enterotoxin A (SEA) detection

16 Oct 2018

We describe the engineering of stable gold nanoparticle (AuNP) bioconjugates for the detection of staphylococcal enterotoxin A (SEA) using localized surface plasmon resonance (LSPR). Two types of AuNP bioconjugates were… Read more
