Teeth-Cleaning Microrobots

Teeth Cleaning Microrobots

Researchers at the University of Pennsylvania have developed prototype teeth-cleaning devices that use microrobots made of iron oxide nanoparticles. With the push of a button, magnets guide the microrobot swarms to form bristles for brushing or an elongated thread for flossing. Notably, the nanoparticles are approved for human consumption by the U.S. Food and Drug Administration.

Two distinct devices are being tested: a mouthguard and a toothbrush. Upon activation, the device distributes a solution of microrobots and hydrogen peroxide into the mouth. The iron oxide nanoparticles kill bacteria and break down plaque more effectively than the disinfectant alone. In testing, researchers have removed 100 percent of plaque from a 3D printed model of human teeth and gums, and achieved an 80 percent success rate in animal testing. Work continues to increase the system’s effectiveness and shorten the cleaning time, which currently ranges from five to 10 minutes.

Tick Talk

Spring officially sprung on March 21. We have turned our clocks ahead. We are looking forward to warm winds, sunny skies and the smell of fresh cut grass. The daffodils and tulips have recently bloomed and we are just starting with the yard work that comes with the warmer weather.  Sadly, another season has started ramping up.  Tick season.

•             The best form of protection is prevention. Educating oneself about tick activity and how our behaviors overlap with tick habitats is the first step.

•             According to the NJ DOH, in 2022 Hunterdon County led the state with a Lyme disease incidence rate of 426 cases per 100,000 people. The fact is ticks spend approximately 90% of their lives not on a host but aggressively searching for one, molting to their next stage or over-wintering. This is why a tick remediation program should be implemented on school grounds where NJ DOH deems high risk for tick exposure and subsequent attachment to human hosts.

•             Governor Murphy has signed a bill that mandates tick education in NJ public schools. See this for the details.  Tick education must now be incorporated into K-12 school curriculum. See link:

•             May is a great month to remind the public that tick activity is in full swing. In New Jersey, there are many tickborne diseases that affect residents, including Anaplasmosis, Babesiosis, Ehrlichiosis, Lyme disease, Powassan, and Spotted Fever Group Rickettsiosis.

•             For years, the focus has mainly been about protecting ourselves from Lyme disease. But other tick-borne diseases are on the rise in Central Jersey. An increase of incidence of Babesia and Anaplasma are sidelining people too. These two pathogens are scary because they effect our blood cells. Babesia affects the red blood cells and Anaplasma effects the white blood cells.

•             Ticks can be infected with more than one pathogen. When you contract Lyme it is possible to contract more than just that one disease. This is called a co-infection. It is super important to pay attention to your symptoms. See link.
