• Tiny whispering gallery
  

  Nanotechnology has already made it to the shelves of your local pharmacy and grocery: nanoparticles are found in anti-odor socks, makeup, makeup remover, sunscreen, anti-graffiti paint, home pregnancy tests, plastic beer bottles, anti-bacterial doorknobs, plastic bags for storing vegetables, and mor more

• New nanochemistry technique encases single molecules in microdroplets
  

  Inventing a useful new tool for creating chemical reactions between single molecules, scientists at the National Institute of Standards and Technology (NIST) have employed microfluidics—the manipulation of fluids at the microscopic scale—to make microdroplets that contain single molecules of interes more

• SLAC researchers reveal the dance of water

  Water is familiar to everyone - it shapes our bodies and our planet. But despite this abundance, the molecular structure of water has remained a mystery, with the substance exhibiting many strange properties that are still poorly understood. Recent work at the Department of Energy's SLAC National Ac more

• Automated Dynamic Light Scattering
  

  DLS analysis is a widely applied, non-invasive method for measuring the effective size of molecules in solution. This technique yields valuable information for the characterization of molecules and particles. It facilitates formerly laborious and time consuming measurements, e.g. screening for aggregates or determining optimal crystallization conditions for proteins. The Wyatt Plate Reader is the instrument of choice for any application where molecular size, stability and aggregation are of interest. It reads industry standard microplates with up to 1536 samples automatically and temperature-controlled, if desired. The applications of the technique are wide ranging and include many of the fastest growing areas of research - proteins, biomaterials, liposomes and micelles as well as the established uses for particle sizing and aggregation detection. Conscious of the numerous characterization challenges in the area of drug delivery systems and therapeutic antibodies more

• Chemical Analysis in a Drop: A Dynamic Surface Tension Detector (DSTD) for Polymer and Protein Characterization

  Abstract A dynamic surface tension detector (DSTD) for the multidimensional analysis of polymers and proteins in aqueous solutions is reviewed. The DSTD is briefly compared to other instrumental methods for the measurement and evaluation of time‐dependent surface tension assessment. The dynamic more

• Wrapping of ellipsoidal nano-particles by fluid membranes

  Membrane budding and wrapping of particles, such as viruses and nano-particles, play a key role in intracellular transport and have been studied for a variety of biological and soft matter systems. We study nano-particle wrapping by numerical minimization of bending, surface tension, and adhesion en more

• Sensors, Vol. 13, Pages 5857-5869: Position Measurement/Tracking Comparison of the Instrumentation in a Droplet-Actuated-Robotic Platform

  This paper reports our work on developing a surface tension actuated micro-robotic platform supported by three bubbles (liquid environment) or droplets (gaseous environment). The actuation principle relies on the force developed by surface tension below a millimeter, which benefits from scaling laws more
