Label-Free Detection Of Nanoparticles Using Depth Scanning Correlation Interferometric Microscopy

Autor: Hakan Urey, Ugur Aygun, Ayca Yalcin Ozkumur

Publikováno v: Scientific Reports
Scientific Reports, Vol 9, Iss 1, Pp 1-8 (2019)

Single particle level visualization of biological nanoparticles such as viruses and exosomes is challenging due to their small size and low dielectric contrast. Fluorescence based methods are highly preferred, however they require labelling which may

Label-Free And High-Throughput Detection Of Biomolecular Interactions Using A Flatbed Scanner Biosensor

Autor: Oguzhan Avci, Ayca Yalcin Ozkumur, Ugur Aygun, Elif Seymour, Hakan Urey, M. Selim Ünlü

Fluorescence based microarray detection systems provide sensitive measurements; however, variation of probe immobilization and poor repeatability negatively affect the final readout, and thus quantification capability of these systems. Here, we demon
