Imaging the Changing Structure of Matter
A Holy Grail of ultrafast science and technology is to image the changing structure of matter at the nanoscale during the interaction with light. An international collaboration including DESY photon scientists led by Thomas Möller of the Technical University Berlin and Christoph Bostedt of SLAC at Stanford (formerly Technical University Berlin) used intense laser pulses delivered by the FLASH free-electron laser for X-ray scattering from nanoparticles.more

A New Twist to Quantum Dot Tracking - New Nanoparticle Changes Color Continuously
There are three issues, all of which are related to blinking, in quantum dot-based particle/molecule tracking. The recently reported "non-blinking quantum dots" address only one of the three issues. Here we report a new class of quantum dot-based composite nanoparticles that emit fluorescence with continuous intensity and alternating color, effectively addressing all three blinking-related issues, as well as providing greatly enhanced brightness compared with single quantum dots. more
3D Nanoparticle Tracking with Conventional Inverted Optical Microscope
Nanoparticles are becoming ubiquitous in many areas of biology and chemistry where they are finding a myriad of uses, including in arrays as chemosensing and biosensing platforms, as building blocks for more complicated structures, and individually as alternatives to fluorescent molecules and quantum dots as labels in bioanalysis. In colloidal systems, interactions of particles of the order of 100nm to 1mm control the behavioral characteristics, for instance the interaction of fat particles and proteins determine whether milk coagulates into cheese or yoghurt. more
Bifunctional Nanoparticles with Optical Properties
An amorphous-seed mediated strategy has been developed in the Center for Nanoscale Materials Nanophotonics Group for creating bifunctional nanoparticles composed of silver and iron oxide nanodomains. These hybrid particles exhibit unique optical properties due to surface plasmon resonance from the silver and superparamagnetic responses from the iron oxide.more
SFM Tips from the Microwave - Fast Microwave-assisted Synthesis of Carbon Nanotubes
Microwave supported synthesis has developed into a widely used tool in chemistry. We report on an approach that utilizes the different absorption capabilities of different materials for microwaves for the synthesis of carbon nanotubes (CNT) on different substrates. The growth mechanism and the applicability of the CNT growth for functional and structured surfaces, as well as for the fabrication of CNT functionalized SFM tips are summerized. more- Legal
