Upcoming conference presentations and exhibits
“See” us at AAPS PharmSci 2020!
Spectradyne is a proud sponsor of the 2020 American Association of Pharmaceutical Scientists PharmSci 360, October 26-November 5, 2020. We will host a virtual exhibit booth and present a poster describing the advantages of using MRPS to quantify virus entitled “Non-Biological Quantification of Viral Titer: A New Approach.” If you can’t attend, you will be able to view the poster in our library after the show.
Come find us at AiChE 2020!
Spectradyne’s CEO, Jean-Luc Fraikin, will attend the 2020 virtual annual meeting of The American Institute of Chemical Engineers (AIChE), November 16-20, 2020. He will present an invited talk in a session on colloidal dispersions entitled, “Orthogonal Methods are Critical for Characterizing Nanoscale Colloids”.
See you there!
Nanoparticles in sunscreen
Ever wondered what’s in the sunscreen you used all summer? Which brand provides the best value on a dollars-per-particle basis? We used Spectradyne’s nCS1 to find out!

How do researchers use Microfluidic Resistive Pulse Sensing (MRPSTM) to make scientific discoveries?
Here are some examples:
Scientists at John Hopkins University and collaborators at the National Institute of Standards and Technology (NIST) recently released a pre-print article comparing emerging tools for quantifying Extracellular Vesicles (EVs). The study compared Nanoparticle Tracking Analysis (NTA), Single-Particle Interferometric Reflectance Imaging Sensing (SP-IRIS), nano Flow Cytometry and Spectradyne’s Microfluidic Resistive Pulse Sensing (MRPS).

Massachusetts Institute of Technology scientists describe the investigation and measurement of chiral supraparticles with applications to drug delivery systems, tumor detection markers, biosensors, and other biomaterial-based devices.

Virtual demo of Spectradyne’s nCS1
Many of you have never seen what it looks like to operate the nCS1, so we put together a short video demonstration. This 13-minute video will walk you through a “virtual demo” of the nCS1: from loading the sample into a microfluidic cartridge to producing a final report. You will see how easy it is to get high quality, high resolution nanoparticle size and concentration data from the nCS1 in just minutes. Once you’ve seen this video, you will be ready to send us samples to see your own data in high definition!
