Manipulating biological samples in microliter droplets has vast potential in molecular diagnostics. We present a system for the two-dimensional (2D) magnetic manipulation of aqueous droplets suspended in silicone oil as a platform for on-chip bioanalysis. ...
Self-assembled monolayer (SAM) films have attracted immense attention for both fundamental and applied research. A SAM is composed of a large number of molecules with a head group that chemisorbs onto a substrate, a tail group that interacts with the outer ...
In this project, we intend to use inkjet-based delivery of functional liquid droplets on pre-structured surfaces for the directed (self-)assembly of micro/nano-objects as experimental platform to build up and validate multi-level models of micro-droplet de ...
We present a microscopic theoretical analysis of time and spatially resolved photoluminescence of naturally occurring quantum dots induced by monolayer fluctuations in the thickness of semiconductor quantum wells. The analysis is based on a recently develo ...
A modified vancomycin binding pocket (D-O-E ring) incorporating a CHNHCOR function at the AA4 position is designed and synthesized. Potent bioactivities against both sensitive- and resistant-strain are found for some of these compds. (MIC 4 micro g/mL agai ...
Gold nanoparticles with hydrophobic surface have been deposited on a silicon substrate chemically patterned by reactive ion etching through a stencil mask and chemical vapour deposition of alkyl silanes. After deposition by dipping and adequate rinsing, th ...
A novel UV-curable low-stress hyperbranched polymer (HBP) micromolding process is presented for the fast and low-temperature fabrication of hydrophilic microfluidic devices. Process, material and surface properties of the acrylated polyether HBP are also c ...
The fluorine incorporation into HfO2 with oxygen vacancies has been investigated using first principles calculations. The authors show that atomic fluorine can efficiently passivate the neutral oxygen vacancy with excess energies of 4.98 and 4.39 eV for th ...
In recent years, superhydrophobic surfaces have attracted a considerable amount of attention from the academic and industrial communities. This growing interest is mainly caused by the fundamental physico-chemical theoretical aspects that remain obscure an ...
Chaotropic agents are cosolutes that can disrupt the hydrogen bonding network between water molecules and reduce the stability of the native state of proteins by weakening the hydrophobic effect. In this work, we represent the chaotropic agent as a factor ...
