Research

Our research encompasses a diverse range of cutting-edge fields, from synthesizing and characterizing natural graphite and graphene derivatives to exploring their functionalization with metallic and magnetic nanomaterials. We're at the forefront of developing innovative biosensors, including electrochemical, optical, and piezoelectric platforms, revolutionizing diagnostics and monitoring in healthcare. Our investigations into agricultural applications focus on nanoecotoxicology and biological models, particularly plants, aiming to understand the impact of nanomaterials on environmental and crop health. In the realm of artificial intelligence, we leverage algorithms to analyze datasets and uncover new insights in materials science and biosensing. Additionally, our biomedical research tackles infectious diseases with novel antifungals, antibacterials, and antivirals. We study bacterial behavior in space to inform space mission strategies, and we're pioneering superconductivity devices.

Portable reduced graphene oxide biosensor for detection of rabies virus in bats using nasopharyngeal swab samples

Challhua, R., Akashi, L., Zuñiga, J., Batista, H. B. D. C. R., Moratelli, R., & Champi, A. (2023)

We've developed a portable biosensor for rapid RABV detection in bat swab samples. Our rGO electrode, coated with cDNA, offers high sensitivity and specificity. Testing with RNA and bat samples showed accurate detection across a wide concentration range (0.145–25.39 ng/μL) and a low detection limit (0.104 ng/μL). With its rapid response time, this innovation outperforms conventional methods, promising on-site RABV detection and potential use for other RNA viruses.
