Hydrogel Microparticles Pave Way for Bedside Diagnostics

Facebook X LinkedIn Email
CAMBRIDGE, Mass., March 9, 2007 -- An inexpensive method has been created to screen for millions of different biomolecules (DNA, proteins, etc.) in a single sample -- a technology that could make possible the development of low-cost clinical bedside diagnostics. The work, based on tiny customizable particles, could also be used for disease monitoring, drug discovery or genetic profiling. Even though the particles are thinner than the width of a human hair, each is equipped with a barcoded ID and one or more probe regions that turn fluorescent when they detect specific targets in a test sample. Using a new, extremely...Read full article

    monomer
    A molecule that has the ability to chemically combine with other molecules to form a polymer, hence being capable of being polymerized. See polymer; polymerization
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
