Small hydrocarbons and their oxygenated derivatives are critical to atmospheric organic aerosol formation and growth. Secondary organic aerosols (SOAs) constitute a significant portion of total atmospheric organic aerosols, and are often generated through the oxidation of biogenic volatile organic compounds (VOCs) such as isoprene, -pinene, and -caryophyllene. Interfaces of SOA...
The nonlinear optical technique, second harmonic generation (SHG), is applied here for the first time to probe single and double strand DNA (ssDNA and dsDNA) chemically attached to fused quartz/water interfaces. DNA interfaces are often a critical functional component of biodetection, thus, the development of molecular biosensors requires a thorough...
