Undergraduate students will learn the preparation of gold nanoparticles, characterise it and from color change they they will confirm the formation.

Lesson Summary:
Students will review the concept of nanoparticles, why are they different from bulk materials and their preparation in laboratory by sodium citrate using chemical reduction method.

Lesson Objective:
To provide students with an opportunity to develop a laboratory method for the synthesis of gold nanoparticles and compare the change of color of the solution with time. They will also confirm the formation of nanoparticles by simple technique.
