This product was formerly named Nanotrap® Magnetic Virus Particles.

Nanotrap® Microbiome Particles

Nanotrap Microbiome Particles rapidly concentrate microbes from many sample types, eliminating the need for filtration, centrifugation or bead-beating.

Large-scale wastewater surveillance can be used to help communities monitor infection dynamics for SARS-CoV-2 and other microbes of concern. Robust, high-throughput methods based on Nanotrap Microbiome Particles are enabling widespread implementation.

  • Nanotrap particles utilize affinity capture and enrichment to attract and bind low abundance viruses.
  • Methods developed for clinical swab samples, saliva, urine, wastewater and blackwater.
  • Compatible with PCR, sequencing or immunoassay analysis methods.
  • Enables simple, rapid automated or manual methods for preparing wastewater samples for nucleic acid extraction, without filtration, centrifugation or bead-beating.
  • Successfully utilized in high-complexity and point-of-care RT-PCR assays with FDA Emergency Use Authorization for COVID-19.
  • Nanotrap particles do not utilize antibodies or other biomolecules as affinity molecules, which means extended room temperature stability.

Nanotrap Products​

Nanotrap Microbiome A Particles

The Nanotrap Microbiome A Particles have a broad affinity for a wide range of microbes and can capture and concentrate influenza A, influenza B, respiratory syncytial virus, coronavirus 229E, coronavirus OC43, SARS-CoV-2, Zika virus, Chikungunya virus, dengue virus, pepper mild mottle virus, hepatitis A virus and monkeypox virus.

Nanotrap Microbiome B Particles

The Nanotrap Microbiome B Particles have been demonstrated to capture and concentrate a wide range of microbes, including Escherichia coli, Salmonella enterica, Campylobacter jejuni, Listeria monocytogenes, Clostridioides difficile and crASSphage.

Nanotrap Enhancement Reagents​

Nanotrap Microbiome Particles rapidly capture and concentrate microbes from raw sewage requiring no filtration or centrifugation. Using Nanotrap Enhancement Reagents with the Nanotrap particles improves the binding of microbes in these samples, further improving downstream detection of nucleic acids. Automated and manual methods are available.

Traditional Wastewater Processing Method

Traditional methods for processing virus from wastewater samples require multiple time-consuming and laborious steps which severely limit throughput.

Traditional wastewater processing method

High-Throughput Wastewater Processing Method with Nanotrap® Particles

Nanotrap Microbiome Particles rapidly capture and concentrate viruses from raw sewage, requiring no filtration or ultracentrifugation. Automated and manual methods available.

Automated method enables 96 raw sewage samples to be processed in 4.5 h (concentration to RT-qPCR detection/quantification), reducing the processing time by at least 20-fold.

Wastewater Manual Protocol


Wastewater Auto Protocol

Molecular Diagnostics (MDx) are the tests and techniques that have been developed in recent decades that analyze biological markers such as nucleic acids and proteins, to diagnose and monitor disease, detect disease risks and to monitor the effectiveness of treatments. MDx assays are used in prenatal testing, infectious disease testing, cancer and inherited diseases testing.
