Translating sensors from the lab benchtop to a readily available point-of-need setting is desirable for many fields, including medicine, agriculture, and industry. However, this transition generally suffers from loss of sensitivity, high background signals, and other issues which can impair reproducibility. Here we adapt a label-free surface-enhanced Raman spectroscopy (SERS) sensor for SARS-CoV-2 antigens from… Continue reading All That Glitters – Sensors From the Lab to Field

New Paper – How Omicron Finds the Sweet Spot
New paper shows omicron relies more on sugars for infection Omicron and its sublineages remain a major public health concern owing to their high infectivity and antibody evasion. Perhaps the most challenging is that the sensitivity of some of the available rapid tests have been reduced against Omicron, compared to previous variants, forcing people to… Continue reading New Paper – How Omicron Finds the Sweet Spot
Freeman Lab featured on Front Cover of Carolina scientific magazine
Ronit Freeman and the Freeman Lab were featured on the cover of Carolina Scientific, a quarterly research magazine, published by The University of North Carolina (UNC) Chapel Hill. Carolina Scientific highlighted the Freeman Lab’s innovative and cost-effective GlycoGrip test strip, which is an alternative to the RT-PCR testing method used in laboratories to test for the presence of COVID-19… Continue reading Freeman Lab featured on Front Cover of Carolina scientific magazine
NSF Director features Freeman Lab’s COVID-19 testing breakthrough in NSF Quarterly Newsletter
The newly appointed NSF Director has featured the Freeman Lab in his first quarterly NSF newsletter. In this impactful piece, the NSF shines a light on how researchers at the Freeman Lab designed a rapid sensing COVID-19 test to meet the challenge of tracking variants, with a sugar-coated strip advances COVID-19 testing.

Freeman Lab lauded for catalyzing SARS-CoV-2 Research
Funded by RCSA’s swift COVID-19 response, the biomolecular engineering expertise at the Freeman Lab is being lauded as a catalyzing project. Resulting from this award, the Freeman Lab has “developed, patented, and quickly brought to mass-market production a glycopolymer-based lateral flow assay for detecting SARS-CoV-2 and its rapidly emerging variants”. The COVID-19 Initiative is a… Continue reading Freeman Lab lauded for catalyzing SARS-CoV-2 Research
Daily Tarheel Feature: Freeman Lab’s SARS-CoV-2 Test Strip Poised to Democratize testing
The Freeman Lab unveils the new GlycoGrip, a cost-effective sugar-coated COVID-19 testing strip. It’s low-cost, long shelf-life proposition positions it perfectly for low and middle income countries to overcome barriers to testing for SARS-CoV-2. The Freeman Lab’s next steps are requesting FDA approval for the test strips and partnering with a manufacturer to produce the… Continue reading Daily Tarheel Feature: Freeman Lab’s SARS-CoV-2 Test Strip Poised to Democratize testing
Turning the Tables on the virus with Low cost sugar-coated COVID-19 test strips
The Freeman Lab and Researchers at the University of California, San Diego, have developed a low-cost test strip that uses sugar to detect COVID-19 within minutes. “We tapped into nature to reimagine viral diagnostics,” said Ronit Freeman, co-corresponding author of the paper. Freeman is an associate professor of applied physical sciences and biomedical engineering in the… Continue reading Turning the Tables on the virus with Low cost sugar-coated COVID-19 test strips
Sugar-coated COVID-19 test takes advantage of coronavirus’ sweet tooth
Researchers in the Freeman Lab take advantage of the virus’s sweet tooth by creating a sugar-coated COVID-19 test strip. This test strip has been effective at detecting all known variants of the coronavirus, including delta. They work to determine if the self-test known as GlycoGrip can detect infections caused by the omicron variant too. Read… Continue reading Sugar-coated COVID-19 test takes advantage of coronavirus’ sweet tooth
COVID-19 Sensing Paper in ACS Sensors
