Ash Lab works in the area of nucleic acid aptamers, which are single stranded DNA or RNA oligonucleotides having high affinity and specificity to their target. Aptamer binding to its target is utilized in designing new biosensing platforms for disease detection and diagnostics. In addition, the lab also focuses on construction of DNA/RNA based nanoparticles decorated with aptamers and oligotherapeutics such as siRNA for the targeted drug delivery to different cancers.
