    Nanotechnology Research

    Post by classical_algebra on Wed Jan 23, 2013 10:41 pm

    I work in a lab in university that experiments with DNA as a building material.
    We focus on the following:

    a) Make DNA nanoconstructions that are more robust with respect to temperature, pH and metal ion concentration -
    allowing them to be used in a wider range of environments

    b) Enable orthogonal chemical and physical stimuli to activate and deactivate DNA sequence-controlled switches -
    enabling greater control of the design and operation of these systems

    c) Develop systems that allow the control of multiple DNA switches without the addition of external reagents -
    enabling the use of these switches in multiplexed self-contained sensing environments

    d) Develop mesoscale DNA constructions that act as sensors

    So far, the lab as created nanoswitches from DNA, controlled by shining light on it.

    How do you monitor the effects and unintended side effects of activating a switch?

    the switches don't actually do anything, they just change DNA structure

    these experiments are done on pure solutions of DNA, in a controlled chemical setting
    its not switching genes on in terms of gene expression, its using DNA as a building material to make swithces for use in
    nanoscale circuit boards and machinery

    Nice! I've been considering taking a career in nanotechnology myself.

    So this can be considered as biological technology?

    Can't wait till the day I can have a head's up display to remind me of errands and info for tests...
