During an emergency situation, the Laboratory of Optical Biosensors and Functional Nanomaterials of the University of Latvia (head of the laboratory - Dr. Roman Viter) plans to work in accordance with state regulations - works remotely to the maximum and performs synthesis and measurements only in the laboratory.
Currently, the Laboratory of Optical Biosensors and Functional Nanomaterials at the University of Latvia has several active projects where work does not stop:
- "Development of 1D ZnO / Polidopamine nuclear shell nanostructures with improved sensitivity and improved structural, electronic and optical properties" (lzp-2018 / 1-0394), reaserch manager - Dr. Roman Viter
New samples of 1D ZnO / Polidopamine nanostructures are prepared, on the surface of samples viral particles are beeing detected. The production of samples takes place in several steps, which need to be done in person and the whole production process takes about 8 hours. The data obtained after the measurements are processed remotely, obtaining information about the properties of the samples.
- “Investigation of photoinduced processes in one-dimensional ZnO / polidopamine nanostructures” (1.1.1.2/VIAA/2/18/279), reaserch manager - Dr.Viktoriia Fedorenko
Specific optical properties of in laboratory made samples of 1D ZnO / Polidopamine nanostructures are studied using photoluminescence.
- "Creation and development of nanostructural surface for the production of dental implants" (777926-NanoSurf-H2020-MSCA-RISE-2017), reaserch manager - Dr. Roman Viter
Zoom meetings are regularly organized with foreign partners to plan future activities, taking into account current travel restrictions. Together they work remotely on publishing existing results and writing publications.
While it is not possible for other partners to work in person and perform experiments at the moment, UL IAPS Optical Biosensor and Functional Nanomaterials Laboratory tries not to delay work and actively works with Phosphate Buffer (PBS) performing optical testing to study the chitosan decay process and implant optical properties.
Whilst completing the project activities, it is also planned to improve the experimental equipment: by optimizing the electrospinning equipment for the development of nanowires and installing a new equipment for measuring diffuse reflection, which can determine the absorption limit of different materials.
About results so far a publication “Photoluminescence Study of Defects in ZnO Coated Polyacrylonitrile Nanofibers” has been written and acctepted by the “Journal of Physical Chemistry” journal. And new publications are beeing written about current experiments and results.
