Dr. Kolpashchikov’s lab group develops DNA nanomachines for biomedical applications. Their DNA machines can recognize RNA molecules with high selectivity, unwind their secondary structures and either detect or cleave them. The DNA machines can be used as highly specific sensors for biological RNA. Alternatively, they can be used for suppression of cancer cells or RNA-containing viruses. The plan is to use the machines for anti-viral and anti-cancer treatment.

Motivated, open-minded students are welcome in our lab. Students will be involved in all aspects of scientific research including literature search, experiment design, data collection and analysis, poster and oral presentations, publishing in scientific journals. Techniques that students will be exposed in our lab include gel electrophoresis, UV/vis and fluorescent spectroscopy, SELEX, bioorganic synthesis (including DNA synthesis), chromatography (including HPLC), photochemistry and others.


Teaching: Biochemistry I course (BCH4053)

The course is focused on chemical structure and functions of the four major classes of biological molecules in the following order: carbohydrates, nucleic acids, proteins and lipids. The course builds on students’ prior knowledge of physical and organic chemistry to understand architecture of biological molecules and how this architecture makes biomolecules functionally active. The complex molecular interplay is illustrated by protein-nucleic acid interactions, membrane transport and biological signaling. ‘Introduction to metabolism’ prepares students for Biochemistry II course.

Each student in the class receives an individual score by the end of semester. Students who collected the highest scores during previous terms are listed below.
