Accidental nanoparticles in the environment: the nanoplastic pollution problem

When you hear the term “plastic pollution,” what do you think of? If you’re like me, you might picture a pile of garbage on a beach, or microplastic beads inside a fish. Most of us are aware that plastic pollution can be found everywhere. But you might be surprised to learn that "everywhere" in this …

The NSF Center for Sustainable Nanotechnology uses art and story to make the nano world relatable

Lee the nanoparticle (art by Elfy Chiang) This post was originally published on the Lifeology blog on March 25th, 2021. Here at Lifeology, we’ve recently been honored to collaborate with The NSF Center for Sustainable Nanotechnology (CSN)! Together we’ve now created two Lifeology “flashcard” courses about how nanotechnology can be applied responsibly to solve real-world problems like …

Podcast Ep 35. Photographing the Unphotographable

How do you photograph the unphotographable? In this podcast episode we interview MIT research scientist Felice Frankel, who specializes in visualizing science, using pictures to draw audiences in and help scientists more deeply examine their own work, including nanoscale materials that are smaller than wavelengths of light! We also have a mini-interview with graduate student …

Nanotechnology and Modern Agriculture

A brief introduction of nanoparticle applications in agriculture from the Connecticut Agricultural Experiment Station There are currently about 7.67 billion people on Earth, and by 2050 the population is expected to increase to nearly 9.8 billion.1 That is a lot of people who all need to eat. According to the Food and Agricultural Organization of the …

How do we measure the size of nanoparticles in a solution?

The size of the materials in nanotechnology is one of the most important factors that power and define the properties of the nanomaterials. But there are many different techniques for measuring that size, and depending on the measurement methods, the results may vary! It doesn’t mean the actual lengths or diameters of the materials change: …

What gives gold nanoparticles their color?

In a previous post, Can gold melt at room temperature? Melting temperature depression!, we talked about how the color of gold changes from shiny yellow to dark red when it is shrunk down to the nanoscale. We know that lots of materials have interesting properties when they get that small, but why do gold nanoparticles have …

Combining the Old With the New: using nanotechnology to enhance ancient medicines

You walk past a body products store on a weekend shopping trip and are immediately overtaken by fragrance, your nose saturated with floral, sugary and tropical scents. Intrigued by the promise of a candle sale, you venture in, perusing the soaps, mists, and candles. About ten free samples later, you find some products labeled ‘aromatherapy’ …
