In this Science Buddies science project, you'll determine whether silver nanoparticles can have a noticeable antibacterial effect and, if so, what concentration of silver nanoparticles is needed to achieve this effect. You can customize this kit to include the nutrient agar media plates, different graduated cylinders, forceps, E. coli K12, and other supplies needed to complete this experiment.

Have you ever heard that nanoparticles can kill bacteria? You may have even seen some consumer products advertise that they contain antibacterial nanoparticles. A nanometer is one billionth of a meter long. Nanoparticles are usually just a few nanometers in diameter — really, really tiny! So how can something that small kill bacteria which are approximately 700 - 1400 nanometers across? Are they really effective? In this science project you will grow some E. coli bacteria and investigate the effectiveness of the antibacterial activity of silver nanoparticles when the silver nanoparticles are used at different concentrations.

Rated 4 out of 5 by from Great customer service! Mold on several plates. Sara answered all of my questions, made great suggestions, and guided me through the process very skillfully. The plates arrived quickly; however, when we opened the lids, we found mold on three of the ten plates. Happy with everything except the mold.

Rated 1 out of 5 by from not sterile plates I bought these plates to save a few minutes before the lab. Unfortunately, the plates were contaminated and not sterile. 24/30 plates have growth on them.

Rated 5 out of 5 by from Eye droppers are perfect for Cartesian divers My 2nd and 3rd graders loved making the Cartesian divers using a 2 liter clear plastic soda bottle and filling it with water. Then putting just enough water in the eyedropper so when the cap is put on they can squeeze the bottle. The more pressure they put on the bottle the faster it goes. We have contests to see whose eyedropper can drop the fastest. Also who can hold it in the middle the longest. I work outside in an educational environmental setting with no electricity. So when the temperature is 90 degrees Fahrenheit, having the students with their hands and arms in 5 gallon buckets to set the experiment up keeps them cool. It also teaches something about air pressure. The plastic eyedroppers don't work, the glass ones are perfect and much less expensive in bulk than if I would purchase them in a drug store which usually have curved tips and in packs of 2.

Rated 5 out of 5 by from Great forceps I purchased the straight edge forceps for my daughter's H.S. science project. She had to put small disks onto a plate with agar. They worked well for her and were easy to hold and control.
