Molecular Biotechnology

Molecular Biotechnology applies modern techniques of molecular biology in both fundamental and applied research. Examples of such powerful tools include DNA mutagenesis, DNA sequencing, RNA interference, stem cell technology, immunological methods, protein engineering, genomics, proteomics, bioinformatics, gene therapy and cloning techniques. These technologies offer exciting opportunities to understand and control complex systems at the molecular level for applications in healthcare, environmental protection, biofuel production and biosecurity. In Ren lab, for example, molecular biotechnology is being applied in a variety of research projects such as tracking bacterial cells using molecular cloning and bioimaging, sensor development for pathogen detection, novel technology for controlling drug resistant infections.
