Description of the Interactive Tool
This laboratory module focuses on the green and nongreen aspects of noble metal nanoparticles (NPs) synthesis. Nanoscience and nanotechnology have been drawing great attention due to the numerous applications of nanomaterials. This guided, inquiry-based activity explores alternative, green fabrication methods using environmentally friendly reducing agents (e.g., tea extracts, coffee, honey, coconut oil, and banana peel).
The main goal of this laboratory module is to help develop the next generation of environmentally conscious chemists and engineers by introducing them to both the green and nongreen aspects of noble metal nanoparticle synthesis.
The activity promotes system thinking as undergraduate and graduate students from multiple disciplines (chemistry, physics, mechanical and materials engineering, and environmental sciences) were given a common research problem and were allowed to come up with their own educated solution.
Additional material for instructors, students, and lesson plan recommendations are available through supporting information.

Points of Strength
This laboratory activity is suitable for Upper-Division Undergraduate education and attempts to nurture interest towards the nanoscience and nanotechnology areas in young minds and to develop the next generation of environmentally conscious scientists and engineers.
