Controlling Mesopore Size and Processability of Transparent Enzyme-Loaded Silica Films for Biosensing Applications

Heinrich Hofmann, Bernard Wenger, Oswaldo Javier Pérez Anguiano, Raphaël Pugin, Emmanuel Scolan

Silica-based nanoporous thin films including large mesopores are relevant as enzyme supports for applications in biosensing. The diffusion and immobilization of large biomolecules such as enzymes in such porous films require the presence of large mesopores ...

Novel Chemosensors for Biologically Important Analytes

Ziya Köstereli

In this work, fluorescent-based chemosensors for the detection of important analytes in aqueous solution are described. The sensors are based on different detection concepts, including analyte-induced aggregation/de-aggregation, pattern-based sensing and m ...

Pattern-based sensing of aminoglycosides with fluorescent amphiphiles

Rosario Scopelliti, Kay Severin, Ziya Köstereli

A mixture of two amphiphiles with fluorescent head groups can be used as a sensing ensemble for the pattern-based analysis of aminoglycoside antibiotics. In buffered aqueous solution, the amphiphiles form a dynamic mixture of micellar aggregates. In the pr ...

Specific Ion Effects in Amphiphile Hydration and Interface Stabilization

Sylvie Roke, Yixing Chen, Rüdiger Scheu

Specific ion effects can influence many processes in aqueous solutions: protein folding, enzyme activity, self-assembly, and interface stabilization. Ionic amphiphiles are known to stabilize the oil/water interface, presumably by dipping their hydrophobic ...

Wagging the Tail: Essential Role of Substrate Flexibility in FAAH Catalysis

Ursula Röthlisberger, Pablo Campomanes Ramos, Andrea Cavalli, Giulia Palermo, Marilisa Neri

The serine hydrolase, fatty acid amide hydrolase (FAAH), is responsible for the intracellular degradation of anandamide and other bioactive fatty acid ethanolamides involved in the regulation of pain, inflammation, and other pathophysiological processes. T ...

Laser-Heating-Induced Displacement of Surfactants on the Water Surface

Sylvie Roke

We report a combined vibrational sum-frequency generation (SFG) spectroscopy, Brewster angle microscopy (BAM), and ellipsometry study of different surfactants on water as a function of surfactant density. Vibrational SFG spectra of surfactants on the water ...

Investigation of Biophysical Properties of Biomolecules by Means of Atomic Force Microscopy

Jae Sun Jeong

Biomolecules are the building blocks of living organisms and perform the most important functions in a biological process. The aim of biophysics is to understand the biological functions of biomolecules in terms of their structure: structure and function o ...
