Synthesis of Nanoparticles in Recyclopol as a Solvent
Background: A variety of nanoparticles have been synthesized in polyol solvents such diethylene glycol (DEG) and triethylene glycol (TREG). These nanoparticle materials include:
– Gold, silver, platinum, and palladium nanoparticles – Lanthanide nanoparticles – Metal oxide nanoparticles – Semiconductor nanoparticles
Purpose: To investigate if Recyclopol can replace DEG/TREG as a lower-cost, greener solvent for nanoparticle synthesis.
Approach: Synthesize CdSe semiconductor nanoparticles (called “quantum dots”) in TREG as a reference, then adapt the methodology to the unique chemical and physical characteristics of Recyclopol.
Benefit: Quantum dots are of interest for the development of biomedical diagnostic technologies, biological imaging probes, and optoelectronics (e.g. Sony Triluminos TVs). A cheaper and greener synthesis both economical and sustainable.
