Read More Professor Yi Lu from the University of Illinois has developed an aptamer-based method for virus detection that is able to distinguish infective viruses from non-infective virions at concentrations as low as 1 pfu/mL. This technology has been developed on human adenovirus but can be generalized to any virus of interest. Since it is not based on the sequencing of genetic information, it requires no sample preparation and can be completed in ~30 minutes. This technology has great potential utility for diagnostics and environmental testing, specifically water quality testing, for the identification and mitigation of water-borne illnesses including adenovirus.

This technology uses... Read More Researchers from the University of Illinois have developed a highly sensitive, graphene field effect transistor (gFET) that can detect DNA in samples. This technology uses Loop-Mediated Isothermal Amplification (LAMP) and crumpled graphene in order to detect the presence of a target segment of DNA within a provided sample. By using crumpled graphene, gFET, and LAMP Dr. Ganguli's technology is able rapidly detect pathogens using entirely electronic means bringing diagnostics directly to point of care medical practice, all while being less expensive, more sensitive, and quicker than other traditional, gold-standard pathogen diagnostics methods. This technology is even able to detect molecular concentrations down to 8 zeptomolar. Publication: Ganguli, A., Faramarzi, V., Mostafa, A., Hwang, M. T., You, S., & Bashir, R. (2020).

Read More Professor Brian Cunningham's research group at the University of Illinois has created a technology for ultrasensitive detection of gold nanoparticles, allowing different assays and applications. These single step, isothermal, room temperature, one-pot assays can process a sample volume as low as ~20 ul. These assays are performed with an inexpensive, small device based on a low intensity LED (no laser), that allows for simple data quantification by counting (no fancy imaging sensor needed) and multiplexing by sample splitting. Applications of this technology include: Activate Capture and Digital Counting (AC+DC) for detection of miRNA, based on gold nanoparticles tags prepared with DNA toehold probes (DNA-AuNPs). (LOD = 100 aM, 2h; no purification and amplification required) Activate Capture and Digital Counting (AC+DC) for detection of proteins, based on secondary antibody-functionalized gold nanoparticles (2oAb-AuNPs) within 15 min (LOD = 10pg/ml) (pictured below) Targeting Recycling Amplification Process (TRAP) for miRNA detection, based on strand displacement reactions (LOD = 0.1aM, 20 min) Activate Cleve and Count (ACC) for ctDNA detection based on gold nanoparticles released after target recognition by CRISPR/Cas (LOD = 1zM, 60 min) (pictured below Related Technology: Photonic Resonator Absorption Microscopy (PRAM) Recent scientific publications include: A compact photonic resonator absorption microscope for point of care digital resolution nucleic acid molecular diagnostics Single-step, wash-free digital immunoassay for rapid quantitative analysis of serological antibody against SARS-CoV-2 by photonic resonator absorption microscopy Digital-resolution and highly sensitive detection of multiple exosomal small RNAs by DNA toehold probe-based photonic resonator absorption microscopy Other articles: Cancer Center at Illinois program leader develops fast, low-cost blood test for detecting early-stage liver cancer Acceleration of cancer biomarker detection for point of care diagnostics

Read More Researchers from the University of Illinois have developed a COVID-19 testing system named SPOT that consists of a rapid, highly sensitive and accurate assay and a battery-powered portable device. The assay combines RT-LAMP with an Argonaute protein from hyperthermophilic archaeon Pyrococcus furiosus for a precise recognition and cleavage of target DNA in saliva samples. The simplicity of the SPOT system enables rapid diagnosis of COVID-19 without a trained personnel and minimal sample handling.
A Multivalent Cholera Multiepitope Fusion Antigen (MEFA) and Application for Development of Effective Vaccines for Cholera Dr. Zhang from the University of Illinois has developed a promising candidate protein for a vaccine against cholera.

Cholera is an acute, diarrheal illness caused by infection of the intestine with the toxigenic bacterium Vibrio cholerae. The protein is a multiepitope fusion antigen (MEFA), incorporating virulence factors which are conserved across multiple Vibrio serotypes. When administered to animals, the cholera MEFA is broadly immunogenic and induces protective antibodies against Vibrio. Since virulence factors from multiple serotypes are included in the fusion protein, this protection can be extended to the various Vibrio serotypes.
Chimeric Secretory IgA Professor Beth Stadtmueller and Sonya Kumar Bharathkar have created a chimeric secretory immunoglobulin A (cSIgA) with a modified secretory component (SC) that can be used... Read More Professor Beth Stadtmueller and Sonya Kumar Bharathkar have created a chimeric secretory immunoglobulin A (cSIgA) with a modified secretory component (SC) that can be used in therapeutic treatment. The bispecific cSIgA can bind its target antigen and additional ligands by an engineered SC portion, such as toxins or surface antigens. This can be applied to treatment for mucosal infections such as Clostridium difficile.

Read More RT-PCR RNA based approaches, the most popular method for SARS-CoV-2 detection, are limited by large numbers of consumables and reagents required, the need for well-optimized protocols, challenges with mutations, and RNA lingering after infectivity. Researchers at the University of Illinois, led by Dr. Aaron Timperman, have developed a protein-based rapid, reliable and inexpensive nanofluidic/microfluidic system to detect viral proteins with limits of detection at clinically relevant levels. The system receives a sample, purifies the virions, prepares the sample and sprays the sample directly into a mass spectrometry. This protein-based approach allows the collection of additional information such sequence mutations, modifications that affect protein function, and bound antibodies.
