mesoporous nanoparticle for miRNA detection

University of Queensland researchers have developed biosensors that use nanoengineered porous gold which more effectively detect early signs of disease, improving patient outcomes.

Most diagnostic methods use costly materials and are time-consuming and expensive to run, but Ph.D. candidate Mostafa Masud and research supervisors Professor Yusuke Yamauchi and Dr. MD Shahriar Hossain have developed a cheaper, faster and ultrasensitive biosensor for point-of-care testing.

"This new diagnostic technique allows for direct detection of disease-specific miRNA, which wasn't previously possible"

"This is especially important for patients at an early stage of a disease such as cancer, who do not have detectable amounts of other biomarkers, but may have a detectable quantity of exosomal miRNA biomarker."
