1. A portable biodosimetry device for detecting radiation exposure, comprising:

  • a microfluidic biochip comprising;

    a biological sample collection channel module;

    an oligonucleotide extraction biochannel module;

    a hybridization channel module;

    a plurality of fluidic actuators;

    a pump, wherein the pump controls a fluid flow in at least one of the biological sample collection module, the oligonucleotide extraction biochannel module, or the hybridization channel module;

    a power source; and

    a microprocessor coupled to the power source, wherein the microprocessor controls activation of at least one module of the microfluidic biochip;

    wherein,the hybridization channel module comprises an oligonucleotide array;

    the oligonucleotide array of the hybridization channel module comprises a plurality of oligonucleotides, where an oligonucleotide of the array will hybridize under stringent conditions to a gene expression product of a radiation responsive gene; and

    the biological sample collection channel module, the oligonucleotide extraction biochannel module, and the hybridization channel module are fluidically coupled and wherein the plurality of fluidic actuators are each individually controlled by the microprocessor.
