Our latest webinar


April 1, 2020 Webinar

Control your experiments – why particle concentrations matter

Given the necessary technology, it’s unlikely any scientist would consider comparing the efficacy of two particle-based therapeutics without controlling for equal dose. But if your particle analysis technology is off by an order of magnitude or more, isn’t this what you’re doing? Learn how you can reduce variability in your experimental outcomes by measuring concentration more accurately with Spectradyne’s nCS1.

Our new webinar will be held April 1, 2020 at 1 pm eastern time – watch here.

Recent publications using the nCS1TM


Spectradyne’s technology has proven to be a valuable tool for researchers working with extracellular vesicles (EVs). Here are a couple of recent publications.

This year the value of Spectradyne’s technology has been featured in many refereed articles. Recently, researchers at UCLA studying extracellular vesicles from auditory cells as carriers for drugs and mediators found that MRPS provides them with a deeper understanding of the distribution of their exosomes, in contrast to the incomplete information obtained by nanoparticle tracking analysis (NTA) technology.

Scientists at the Research Centre for Natural Sciences (Budapest, Hungary) coupled Spectradyne’s microfluidic resistive pulse sensing (MRPS) to Flu-SEC (Fluorescence-Size Exclusion Chromatography) to accurately size EV populations and verify the measured fluorescence intensity to the number concentration.

Spectradyne’s nCS1TM

A valuable complement to flow cytometry

Spectradyne received positive feedback from its customers that also use flow cytometry to quantify extracellular vesicles (EVs) or other particles in biological samples. These customers find significant value in Spectradyne’s non-optical detection method to deliver new insights into sample composition that cannot be obtained by optical methods such as flow cytometry alone. With more accurate concentration and size measurements by the Spectradyne’s nCS1TM, researchers found the coupling of MRPS to fluorescence-based flow cytometry provide for a unique and complete sample analysis of small particles in heterogenous biological samples.

A new way to understand your data

At Spectradyne, we love data and we’re always looking for more ways to dig into what they can tell us. The MRPS technology in the nCS1 allows us to capture the time trace of each individual particle as it moves through the sensing zone. We use the recorded data to generate high-resolution information on size and concentration. To better appreciate the particles this way, we can turn the time-domain data into audio file for a truly unique listening experience.
