Acoustic Excitation in PCR
Imagine you have a pot of water on the stove, gently simmering. Now, let’s say you have a superpower to generate sound waves that can shake the water molecules like a tiny earthquake. What would happen?
Well, in the world of PCR, that’s exactly what happens! Acoustic excitation uses sound waves to give the DNA molecules in your PCR reaction a gentle “shake-up.” This shaking helps the molecules move around more freely, making it easier for them to find their “dance partners”, the primers.
Thermal Cycling
Once the DNA molecules have found their partners, we need to heat them up to “unzip” the double-stranded DNA. This is where thermal cycling comes in. The PCR machine cycles through three different temperatures:
- Denaturation: High temperature (95°C) to separate the DNA strands.
- Annealing: Lower temperature (50-65°C) to allow primers to bind to the single-stranded DNA.
- Extension: Moderate temperature (72°C) to enable DNA polymerase, the “master builder,” to add new nucleotides to the growing DNA strand.
Key Researchers
Like all scientific discoveries, acoustic thermocycling had its pioneers. Three notable names stand out:
- Stephen Quake: Developed microfluidic devices that use sound waves for ultrafast PCR.
