The development of quantum dots has won the 2023 Nobel Prize in Chemistry for chemists Moungi Bawendi and Louis Brus, and physicist Alexei Ekimov. Quantum dots are a new class of nanoparticles roughly a few billionths of a meter across that have significant implications.

They are illuminated by light, which energizes the electrons within them. These energized electrons subsequently release energy as fluorescent light, with smaller dots appearing blue and larger dots appearing red. By using different materials or adjusting the size of quantum dots, chemists can alter their properties.   

Ekimov and Brus independently demonstrated the ability to precisely control the size of these nanoparticles, and Bawendi developed a method to precisely control their growth. These breakthroughs have opened up potential applications for various fields, including medicine and technology. For example, quantum dots could be used to improve the efficiency of LED lights and help surgeons identify tumors by injecting fluorescent dots into the body. The dots also have potential applications in solar cells and quantum computers.

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.
