01 / CHALLENGE
Why this work matters.
Nucleic-acid isolation is a key preparatory step in molecular diagnostics and motivates miniaturized workflows.
02 / APPROACH
How it works.
A PDMS microfluidic chip with continuous baffles and spiral channels integrates magnetic-bead capture, ethanol-buffer washing and elution. Purified PCR product was assessed by spectrophotometry and downstream PCR amplification.
