​Dr Al-Sulaiman's research focuses on the development of next generation biosensing platforms to detect an emerging class of disease biomarkers called cell-free nucleic acids including microRNA and cell-free DNA. At the intersection between polymeric biomaterials and microtechnologies, her research includes advancements in hydrogel beads, microparticles, microneedles and microarrays. She is also interested in single-molecule detection technologies, namely nanopore sensors, for the detection and characterization of rare disease biomarkers. Dr Al-Sulaiman's research aims to tackle urgent clinical needs including early detection and monitoring of cancer and Alzheimer's disease in addition to understanding the skin microbiome.
