Abstract

Three quantum dots (QDs) nanofluids modified with different lengths of PEG chainsare synthesized, and the property-structure relationship of QDs nanofluids is established, to achieve QDs nanofluids with tunable fluidic or optical performance. Notably, the proposed QDs nanofluids demonstrate a selective response towards Cu(2+)-based on both fluorescence and contact angle.

Keywords: Cu2+ ions; fluid sensors; nanofluids; quantum dots; temperature dependent.
