GREEN NANOCHEMISTRY: SYNTHESIS OF SILVER NANOPARTICLES
Nanotechnology is a field of technology that is described as the control and manipulation of matter in the 1 to 100 nanometer (nm) range.A nanometer is one billionth of a meter, or one millionth of a millimeter. To put it in perspective, an average sheet of copier paper is about 100,000 nanometers thick so a nanometer is 100,000th the thickness of a piece of copier paper. Certain materials, when prepared at nanoscale levels, display different physical and chemical properties than those of the same materials prepared on a larger scale.
- In this activity, students synthesize silver nanoparticles from silver nitrate.
- The particles are synthesized in glucose and starch, as opposed to the more hazardous reagents typically employed.
- Kit contains enough materials for 15 groups.
- Teacher's Manual and Student Study Guide copymasters are included.

What Educators are Saying About Geyer
Justin has been nothing but helpful and professional in my requests for these Boeing Defense requirements. He has been able to answer my questions and concerns quickly, and helped in securing the order that I may have made with another supplier had be not been the value-add that he is to your company. I hope his merit raise this FY was "exceeds expectations".
Jesse C...I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!
John C.The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.
Robert C.I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.
Mischelle F....I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
