Interferometric Biosensor Being Developed for Rapid Detection of Diseases, Viruses, and Chemicals
The rapid, accurate, and specific detection of various diseases, viruses, and chemicals has long been an objective of the medical, animal health, chemical, and agricultural industries globally. Often, developed detection technologies and methods can achieve only two of the three objectives (speed, accuracy, specificity), with RNA-based PCR approaches being commonly accepted as the most robust in terms of diagnostic accuracy and specificity. However, the ability to successfully meet all three objectives simultaneously has remained somewhat illusive for diagnostic and chemical applications alike. Through many years of research and development, researchers at the Georgia Tech Research Institute (GTRI) have refined a technology that holds promise for reducing the tradeoff between speed, accuracy, and specificity. This technology is an innovative interferometric biosensor that can be configured to rapidly detect a variety of pathogens and chemicals.
How It Works
The science behind the sensor is a concept known as interferometry that exploits the interference of light waves to precisely determine the rate at which target particles attach to the sensor’s surface. Specifically, light from a laser diode is coupled into an optical waveguide through a grating and travels under one sensing channel and one reference channel. The best way to visualize this is to think about a microscope-like glass slide with two little troughs etched onto the surface with a laser light shining into one end of the slide.
Handheld Device Quickly and Accurately Detects Pathogens and Contaminants
for Health, Food and Industrial Applications
Valdosta, Ga. (March 16, 2021) – Salvus™, part of the CJB family of companies, today
announced the upcoming commercialization of a novel interferometric platform that provides
highly accurate detection of contaminants or pathogens in many industries. Applicable in human
and animal health, agriculture, water quality management, food processing and the chemical
and transportation industries, Salvus detection technology features handheld detection in
minutes with extreme specificity and at parts per trillion accuracy in many applications. The
platform is proven to detect SARS-CoV-2, the virus that causes COVID-19, with sensitivity and
specificity comparable to molecular tests, as well as dozens of other potentially dangerous
pathogens and chemical contaminants.
The Salvus detection system consists of a lightweight, handheld analyzer and a disposable
cartridge – both patent pending – that is adaptable to many
point-of-care and on-site uses ranging from airports and
health care facilities to farm fields, tanks and animal
enclosures. Individual cartridges can be developed and
manufactured for simultaneous detection of multiple
contaminants, chemical or biological, providing fast and
precise results. Additionally, this easy-to-use innovative
detection technology can be operated with minimal training.

CJB and National FFA Launch a Cooperative Venture
The CJB companies (CJB Industries, Inc. and CJB Applied Technologies, LLC) have announced a cooperative venture with National FFA to benefit the companies who support National FFA as well as the National FFA itself.
Beginning October 1, 2020 and through December 31, 2020, CJB will launch “Blue” hand sanitizer and make it available to purchase by companies supporting National FFA. The product will be sold AT COST by CJB and will only be available for purchase by National FFA supporting companies. “Blue” hand sanitizer will be sold in 4 X 1 gallon bottles per case, pumps included. A donation of $1 will be made to National FFA, in the name of the purchasing company, for every gallon of “Blue” sold. Outsource Logistics, Valdosta, GA will provide fulfillment and logistics services for the program and will also do so at cost.
“We are pleased to offer “Blue” hand sanitizer to National FFA supporters,” said CJB Applied Technologies’ Chief Commercial Officer, Jim Loar. “Providing Blue at cost, plus the $1 per gallon donation to FFA, is meant to be an economic benefit to FFA supporters as well as a positive financial impact to National FFA. We hope that all FFA supporting companies will take advantage of this opportunity. The CJB team is ready to receive case, pallet and truckload orders,” says Loar. Orders can be placed online at www.cjbappliedtech.com.
“As we continue to navigate through this uncertain time together, we are greatly appreciative of the support for FFA from CJB, and we are happy to see the alignment with, and cooperation of, our partners while keeping everyone safe and healthy,” said Molly Ball, President of the National FFA Foundation and Chief Marketing Officer of the National FFA Organization.
