The Variable Pressure Module (VPM) from Izon Science extends the capabilities of Izon’s qNano and qViro instrument range, providing a comprehensive nanoparticle analysis system. Researchers using Izon’s nanoparticle analysis system can measure and characterize virtually all particles including nanoparticles, viruses, bacteria and bioparticles such as exosomes and liposomes. Particle concentration, electrophoretic mobility, size and aggregation kinetics can all be analysed. Real-time reaction monitoring allows users to design and test nanoparticle systems by analyzing the changes in particle properties as various modifications are applied. This is useful for bio-nano work, drug delivery research or development of diagnostic applications. Izon’s qNano and qViro instruments use tunable nanopores to measure individual particle properties as they cross the nanopore. Izon’s Variable Pressure Module (VPM) provides precise control of liquid flow in addition to the standard electrophoretic operation of nanopores. The ability to vary pressure, electrophoretic force and nanopore size in real time, while monitoring the output is what provides the broad range of capabilities. These analytical tools are expected to result in novel research in a number of nanoparticle related fields. Charged and uncharged particles can now be detected. By finely controlling and balancing electrophoretic and pressure forces exerted on the particle, detailed mobility and charge information can be extracted in a wide range of pH and electrolyte environments.

Striving Toward Secondary GoalsLate last month, Republican presidential candidate Newt Gingrich stunned most everyone when he declared his promise that "by the end of my second term, we will have the first permanent base on the moon." While I don’t fault Gingrich for dreaming and trying to set high standards and goals, I can’t help but think of the enormous amount of known and unknown variables that significantly deter this accomplishment...continue
