Nano-Link will be upgrading our website this summer!  Over the weekend of June 17-18 our site will be moved to a different home, with a new look and feel and lots of great new features.  

Our web address is going to stay the same, so you still will find us at http://www.nano-link.org.  But behind the scenes we are gong to be moving to different web and email servers.  As we are starting to make the changes needed for this, you may find that certain things on our current site aren't quite the way they used to be leading up to the move. 

If you have any issues, please contact us immediately at help@nano-link.org so we can help you get the answers and resources you need! 

Nanoparticles and Sunscreen

In this activity, students are introduced to the function of sunscreen and learn how nanoparticles can be used to protect people from ultraviolet radiation.  They use photochromic paper as a UV sensor, place samples of different types of sunscreen over this UV sensor, expose their samples to UV light, and determine the level of exposure through each type of sunscreen.  Using these tools, students compare the effectiveness of conventional (chemical-based) and nanoparticle-based sunscreens.

List of Required Materials

*Bottle of sunscreen
*Photo chromatic paper
Straight edge
Light sources
Shallow dish

*Denotes materials sent by Nano-Link to the educator

To request materials you must complete the "NIP Registration Form" available in the Nano-Infusion menu.
