DNA separation by silica adsorption - Wikipedia

Methods using silica beads and silica resins have been created that can isolate DNA molecules for subsequent PCR amplification. However, these methods have associated problems. First, beads and resins are highly variable depending on how well they are packed and are thus hard to reproduce. Each loading of a micro-channel can result in a different amount of packing and thus change the amount of DNA that adsorbed to the channel. Furthermore, these methods result in a two step manufacturing proc…
