Thursday (05/19/2022). The Faculty of Mathematics and Natural Sciences (FMIPA UI) held the 5th MIPAtalk Series webinar. The title of the webinar in this series is “Nanoplasmonic Applications for Biological Sensors and Materials”. The webinar invited Dr. Ferry Anggoro Ardy Nugroho, a researcher at Department of Physics and Astronomy, Vrije Universiteit AmsterdamNetherlands as a resource person. Dr. Ferry has extensive experience and publications in the field of materials science, nanotechnology, sensors, and energy.
This activity took place virtually. Not only held through the Zoom Meeting platform, MIPAtalk was also broadcast live on the official YouTube channel of FMIPA UI (FMIPA UI Official) so that it can be watched by the general public.
The agenda was opened with remarks from Dr. Dipo Aldila, S.Si., M.Si. as the Manager of Research and Community Service.
“MIPAtalk is a form of commitment from the Faculty that is passed down from the University,” said Dr. Dipo opening his speech.
“We need to-update our science. Science continues to develop so we need to listen to scientific progress and here are some areas of science that are the focus, one of which will be presented by Mr. Ferry. We hope that this activity will be a tool to increase our insight as an opportunity for cooperation or research in the future,” said the Epidemiology Mathematics expert.
Entering the main session, namely the presentation by Dr. Ferry Anggoro Ardy Nugroho. The material presented includes an introduction nanoplasmonics, sensor application nanoplasmonics, and its latest developments.
In his presentation, Dr. Ferry explained that the phenomenon behind nanoplasmonics is when light waves interact with metal nanoparticles. The interaction of light with metal nanoparticles produces “color” on the nanoparticles. The difference in “color” on metal nanoparticles is due to the effect of plasmonics. Dr. Ferry continued, there are two types of sensors nanoplasmonics depending on what changes from the resonance peak. The first is direct (direct), when what changes is the condition of the nanoparticles. The second is indirect (indirect), when what changes is the condition of the nanoparticles. The second is indirect
Basic principles direct plasmonic sensing is when nanoparticles (materials/metals) change. Examples include phase changes (oxidation, hydration, etc.), changes in shape or physical, and changes in temperature. In addition, the basic principles indirect plasmonic sensing is when the conditions around the nanoparticle change.
Censorship hydrogen nanoplasmonics becoming the first sensor with a detection time of less than one second. Its integration with fiber optics could bring the nanoplasmonics platform closer to applications. Then its integration with polymers and 3D printers could produce sensors with high scalability.
Dr. Ferry closed his presentation with a summary of the following conclusions. Sensors nanoplasmonics Dr. Ferry closed his presentation with a summary of the following conclusions. Sensors naoplasmonics very versatile and sensitive with unlimited applications, both biological and material. With the creativity of using the type and configuration of nanoparticles, it can open up many new applications and achievements.
After the presentation session from Dr. Ferry. The webinar was continued with a question and answer session with the webinar participants who were present at the Zoom Meeting. The webinar ended after lasting almost two hours.
