A major biomedical and pharmaceutical challenge is to provide quick,
safe and effective
treatment of various types of human pathophysiology. However, the lack of rapid, reliable
and robust techniques for detection of disease biomarkers in biological samples represents
the major bottleneck in screening of different pathological conditions in humans. The major
disadvantages of the available diagnostic assays include
the high production costs, inaccuracy,
poor sensitivity and lack of reproducibility, which hamper the transition of biomedical
diagnostics from specialised laboratories to clinical settings. Therefore,
there is an urgent need
for the development of novel advanced technologies allowing
in situ
nucleic acid detection for
diagnostic purposes to improve health outcomes through early-stage diagnosis, more precise
monitoring of therapeutic treatments and disease prognosis.
With regards
to therapeutic treatments, traditional targeting of
downstream
pathways
to treat the physiological abnormalities of disease states at the level of expressed proteins
is proving increasingly difficult and often suffers from off-target effects and severe toxicity.
A promising alternative to small molecular drugs is based on the RNA-targeting approaches,
which offer the advantages of absolute selectivity, improved potency and reduced toxicity.
This talk is focused on the development of new strategies
for development of novel
molecular diagnostics and therapeutics based on the functional bioconjugates of nucleic acids
and peptides.
Our research focus involves the design and fabrication of novel functional biomaterials
with controlled chemical and biological properties, which can be used as a basis for devel-
opment of clinically- and commercially-useful
diagnostics, reagents and therapeutics in order
to provide solutions to complex biological and biomedical grand challenges, unmet by conven-
tional approaches. To achieve this, we work at the
interface between synthetic, analytical,
physical and computational chemistry with structural and chemical biology and use biologi-
cally-friendly building blocks (
e.g.
nucleic acids and peptides), which are bio-degradable and
highly controllable in terms of their structure, properties and function.
These recent advances
open up new exciting avenues for development of a novel technological platform for rapid
detection and effective treatment of human pathophysiology.
