4. 제 목 : Synergistic combination of functional DNA and nanomaterials for environmental and biomedical applications
Recently DNA has recently been recognized as a programmable and tailorable material with functional activities. In the first part, an effort to use UO22+ (uranyl) specific DNAzyme with plasmonic gold nanoparticles for development of highly sensitive and selective colorimetric uranyl sensors will be introduced. In addition, a method to deliver DNA aptamers by gold nanoparticles to cancer cell nucleus and release them by NIR ultrafast femtosecond pulsed laser for cell nucleus specific targeted therapy will be discussed. These interesting functional and structural properties of DNA can provide new opportunities to develop dynamic DNA structures for potential use as environmental analysis and drug delivery agents.
