Claim 14:
15. The nanofluidic chip of claim 1, wherein the nanofluidic chip is fabricated by:
synthesizing the silica spheres;
functionalizing a surface of the silica spheres to form functionalized silica spheres;
functionalizing a surface of microchannels in a microfluidic chip to form a functionalized microfluidic chip;
assembling the functionalized silica spheres in microchannels of the functionalized microfluidic chip to form a precursor nanofluidic chip; and
forming calcium carbonate nanocrystals on functionalized surfaces of the precursor nanofluidic chip to form the nanofluidic chip.
