1. A method of amplifying target nucleic acids in skin-encapsulated capsules comprising:

  • a) providing an aqueous phase comprising at least about 0.01% by weight of a skin-forming protein, an amplification reagent mix and target nucleic acids;

    b) forming an emulsion comprising droplets of said aqueous phase disposed in a continuous phase comprising an oil and a negatively charged ionic surfactant;

    c) heating said emulsion to at least about 50°

    C. to create an interfacial skin between each droplet and the continuous phase, such that said droplets form skin-encapsulated capsules;

    d) amplifying said target nucleic acids in said capsules; and

    e) detecting amplification of said target nucleic acids.
