Mangrove soil as a natural catalyst for green synthesis of silver nanoparticles.

ABSTRACT:

Introduction

Mangrove ecosystems host diverse biogeochemical pathways that enhance their resilience against a wide range of pollutants, from heavy metals to hormones. The unique combination of extreme physicochemical soil conditions and the anaerobic metabolism of mangrove microbiota creates favorable conditions for nanoscale processes.

Methods

The presence of naturally occurring nanoparticles in soil extracts from Costa Rican mangroves at Punta Morales and Cahuita was characterized. Furthermore, we evaluated the ability of these soil extracts to catalyze the formation of silver nanoparticles (AgNPs) under sunlight in saline environments (28°C-31°C within 15 min). Characterization techniques such as transmission electron microscopy (TEM) with selected area electron diffracti
