  • Now in 3-D: Video of virus-sized particle trying to enter cell

    Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed could help scientists learn more about how to deliver drugs via nanopar more

  • Smartphone 'microscope' can detect a single virus

    Aydogan Ozcan, a professor of electrical engineering and bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, and his team have created a portable smartphone attachment that can be used to perform sophisticated field testing to detect viruses and bacteria without the n more

  • Icy exposure creates armored polymer high tech foams

    Chemists and engineers at the University of Warwick have found that exposing particular mixtures of polymer particles and other materials to sudden freeze-drying can create a high-tech armored foam that could be used for a number of purposes, including a new range of low power room temperature gas s more

  • Do you see the complete picture?

    Gel permeation chromatography (GPC) or also named size exclusion chromatography (SEC) is the most often used method for determining the molecular weight of natural and synthetic macromolecules. One specific strength of this method lies in the fact that by the separation process the whole molecular weight distribution is obtained. The molecular weight distribution contains much larger information for the characterization of polymer samples compared to a single value. more

  • Optimization of Transfection Conditions for the Human HL-60 Promyelocytic Leukemic T-Cell Line Using FuGENE® HD Transfection Reagent

    Transfection is commonly performed to introduce many different types of molecules (plasmid DNA, RNA, siRNA, miRNA) into eukaryotic cell lines. Once inside, these molecules can be expressed in a transient or a stable fashion. In the case of transient transfection, molecules do not integrate into the host cell genome and are only expressed for approximately 24 hours - 96 hours post-transfection. more

  • Field-Flow Fractionation - The Universal Separation Principle for Particle and Macromolecule Characterization

    High molecular weight polymers, bio molecules or particles in a range of a few nanometers up to several microns are more and more important in science and technology. Many applications are based on the specific properties of these materials. For this reason, an exact knowledge of the molar mass or particle sizes distribution is essential for later application as well as for optimization of the production processes or quality control. In addition the knowledge about the chain structure of macromolecules or biopolymers as well as about the shape of particles is often necessary. For this reason those samples, which often can be very complex systems, have to be separated according to parameters such as e.g. hydrodynamic volume or molecular weight. After the separation process the resulting narrow dispersed fractions are detected with different techniques. more
