anotechnology and medicine gave birth to the new and promising interdisciplinary research field called nanomedicine.
Thanks to the improvements in both of the nanotechnology and nanomedicine we are able to help and improve people’s
health on the nanoscale. One way is using biosensors that can signalize the existence of pathogens, alien DNA, viruses etc. The
most important features of the nanomaterial to create a biosensor are their shape and stability. Shapes that are the best fit are
elongated and flat nanoparticles such as nanotubes, nanorods, nanowires and nanoribbons. The size of these nanocreations gives
an opportunity to later functionalize them with biological and chemical molecules.
Gold nanoribbons are promising metallic support for biosensors in the nanoscale, and thanks to the development of modern
technology, we are able to create them using various methods. One of them is using oligomeric and polymeric surfactants – surface
active agents, built of hydrophobic and hydrophilic moieties that can wrap around the growing nanoparticles. The properties of
surfactants are helping to stabilize the growth of the specific shape of nanoparticle such as nanoribbons. The conducted study
has been focused on creation of metallic nanoribbons especially gold nanoribbons with the use of various surfactants. The gold
seeds used in the synthesis of nanoribbons have been tested via UV-Vis. Later, properties of synthesized nanoribbons have been
tested with Atomic Force Microscopy and Transmission Electron Microscopy. Relying on those spectroscopy and microscopy
techniques we were able characterize created nanoparticles.
Biography
Joanna Patalas is a student of the 4th year of Medical Physics, Department of Macromolecular Physics, Faculty of Physics, University
of Adam Mickiewicz. She and 3 other students under coordination of prof Maciej Kozak has been working on a project that improves
ways of obtaining specific shape of nanoparticles with the use of oligomeric and polymeric surfactants. Her passion is working for the
improvements in new methods of helping people such as nanomedicine and gene therapy.
