In Vivo Molecular Bioluminescence Imaging: New Tools and Applications

in vivo bioluminescence imaging (BLi) is an optical molecular imaging technique used to visualize molecular and cellular processes in health and diseases and to follow the fate of cells with high sensitivity using luciferase-based gene reporters. The high ...

Advancing Biocapture Substrates via Chemical Lift-Off Lithography

Nako Nakatsuka

Creating small-molecule-functionalized platforms for high-throughput screening or biosensing applications requires precise placement of probes on solid substrates and the ability to capture and to sort targets from multicomponent samples. Here, chemical li ...

The role of the crystalline face in the ordering of 6-mercaptopurine self-assembled monolayers on gold

Klaus Kern

Well-ordered molecular films play an important role in nanotechnology, from device fabrication to surface patterning. Self-assembled monolayers (SAMs) of 6-mercaptopurine (6MP) on the Au(100)-(1 x 1) and Au(111)-(1 x 1) have been used to understand the int ...

The persistence length of adsorbed dendronized polymers

Giovanni Dietler, Michal Borkovec, Plinio Maroni, Andrey Mikhaylov

The persistence length of cationic dendronized polymers adsorbed onto oppositely charged substrates was studied by atomic force microscopy (AFM) and quantitative image analysis. One can find that a decrease in the ionic strength leads to an increase of the ...

NRK1 controls nicotinamide mononucleotide and nicotinamide riboside metabolism in mammalian cells

Johan Auwerx, Carlos Canto Alvarez, Joanna Ratajczak

NAD(+) is a vital redox cofactor and a substrate required for activity of various enzyme families, including sirtuins and poly(ADP-ribose) polymerases. Supplementation with NAD(+) precursors, such as nicotinamide mononucleotide (NMN) or nicotinamide ribosi ...

On the Use of Shape-Constrained Splines for Biokinetic Process Modelling

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

Identification of mathematical models is an important task for the design and the optimization of biokinetic processes. Monod or Tessier growth-rate models are often chosen by default, although these models are not able to represent the dynamics of all bac ...

Surface Structure and Chemistry of Alkanethiols on Au(100)-(1 x 1) Substrates

Klaus Kern

The surface structure of self-assembled monolayers of hexanethiolate (HT) on the Au(100)-(1 x 1) surface has been studied by density functional theory (DFT) calculations and their results compared to scanning tunneling microscopy (STM) and X-ray photoelect ...

A Functional Model of [Fe]-Hydrogenase

Rosario Scopelliti, Xile Hu, Matthew Wodrich, Tao Xu, Simona Mazza

[Fe]-Hydrogenase catalyzes the hydrogenation of a biological substrate via the heterolytic splitting of molecular hydrogen. While many synthetic models of [Fe]-hydrogenase have been prepared, none yet are capable of activating H-2 on their own. Here, we re ...

Biokinetic process model diagnosis with shape-constrained spline functions

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

Model-structure identification is important for the optimization and design of biokinetic processes. Standard Monod and Tessier functions are often used by default to describe bacterial growth with respect to a substrate, leading to significant optimizatio ...

Real-Time Label-Free Direct Electronic Monitoring of Topoisomerase Enzyme Binding Kinetics on Graphene

Klaus Kern, Kannan Balasubramanian

Mono layer graphene field-effect sensors operating in liquid have been widely deployed for detecting a range of analyte species often under equilibrium conditions. Here we report on the real-time detection of the binding kinetics of the essential human enz ...
