DNA nanotechnology uses DNA (or nucleic acids) as a versatile material to rationally engineer tools and molecular devices that can find a multitude of different applications (e.g., in-vivo and in-vitro diagnostics, drug delivery, genetic circuits etc.).<\/p>\n
During this presentation I will introduce the field of DNA nanotechnology and I will talk about some of the most exciting examples of the last decade.<\/p>\n
I will show how to exploit the \u201cdesignability\u201d of DNA to fabricate nature-inspired DNA-based nanoswitches and nanodevices that are specifically designed to undergo a conformational change (switch) upon binding to a specific input (i.e. target). This input-triggered conformational change can be used for diagnostic, drug-delivery or synthetic-biology applications.<\/p>\n
I will demonstrate how to characterize and recreate in-vitro several mechanisms to control the response of DNA-based nanodevices (1-2) and how to regulate their activity with different chemical and environmental stimuli including pH (3-8), antibodies (2-3), enzymes (9), small molecules (10) and electronic inputs (11).<\/p>\n
