Since the COVID-19 pandemic, the need for precise and rapid
molecular diagnosis and testing of viral genomes has significantly increased.
Many countries had to run PCR (polymerase chain reaction) tests, which have a
relatively long turnaround time from sample to result in order to accurately
diagnose the presence of SARS-CoV-2. Instead of waiting on results for hours,
what if future pandemics could be more easily diagnosed within
minutes? What if molecular diagnosis could become more readily available in our
daily lives so that everybody can easily test themselves on viral disease
markers instead of second-guessing and relying on symptoms? What if we could
develop molecular diagnosis tests with high sensitivity and specificity that
can then detect early-onset diseases?
Youngeun strongly believes the key answer to all the
questions above lies in DNA, a powerful material that can be used beyond the
genetic code of life. DNA strands are programmable (enabling one to program and
synthesize a desired sequence), adjustable (allowing one to dynamically control
or tune the length and structure based on input stimulus), and structurally
stable (as discovered in fossils from ancient times). Youngeun has studied
DNA and developed novel techniques in the past 10+ years, including
transmutable nanoparticles with reconfigurable DNA strands and single-strand
recombinase polymerase amplification (ssRPA) techniques that allow SARS-CoV-2
detection within minutes. Her research also led to an opportunity in founding a start-up company (3EO Health) as one of the scientific
co-founders. She has recently started as an assistant professor in Materials
Science and Engineering at Seoul National University to carry on her enthusiasm
and passion for developing new materials using DNA.
Youngeun plans to encourage and mentor younger students to study and
research nucleic acid-based strands as next-generation materials, in hopes of
not only enabling rapid day-to-day molecular diagnosis, but also developing
materials with new properties – all utilizing DNA, a fantastic material nature
already gave us.
