Overview

Controlled experiments reveal how polymer length affects DNA adsorption on minerals, implying implications for environmental persistence.

Key Points

  • Shorter dna polymers may persist longer in natural environments, indicating future implications for eDNA applications.
  • Adsorption increases with longer polymer lengths for fe(iii)-(oxyhydr)oxides and clays but decreases for hydroxyapatite.
  • Controlled batch experiments showed competitive adsorption dynamics significantly alter based on polymer length and order of addition.
  • Understanding these dynamics helps explain the factors influencing dna preservation and its role in biogeochemical cycles.
