Paper Title:
Quantum Dot Uptake in the New Zealand Environment
  Abstract

The use of quantum dots (QDs) for different applications such as biomarkers has increased in the past decade. Here we report on the uptake of fluorescent QDs into agricultural soil, and transport following their ingestion by the larvae of some common lepidopteran insects. Some QDs were leached through soil but their emission was quenched due to geo-effect. In contrast, fluorescence was still seen in leafroller larvae fed with these QDs and in their frass. Abbreviations: QD, quantum dot; NPs, Nanoparticles; Cys, cysteine; Gly, glycine; MPA, mercaptopropionic acid; MSA, mercaptosuccinic acid; AM, 2-aminoethanethiol; Na2EDTA, ethylenediaminetetraacetic acid disodium salt; PV, pore volume
