Characterization of nanospherical silicate particles by nitrogen adsorption and SEM imaging: NS (black), NS-G (blue), NS-T (green), and NS-B (red).

<p><b>A.</b> Nitrogen adsorption/desorption isotherms. <b>B.</b> Pore size distributions. <b>C.</b> SEM image. <b>D.</b> Particle diameter distribution determined from SEM images.</p

Recovery of RNA adsorbed onto sorbents following storage at 4°C.

<p>Data is presented as the ratio of the RNA recovered on a given day to that recovered for the same sorbent on day one of the experiment. Recovery of RNA from NS (black), NS-G (blue) NS-T (green), and NS-B (red) sorbents. An RNA control in water under identical storage conditions was also monitored over this time period (gray).</p
