We are honored to announce that Professor Paulo César De Morais, from the Catholic University of Brasília, Brazil, will be delivering a Keynote Virtual Presentation at the International Congress on Materials Science and Nanotechnology, scheduled for November 20-22, 2025, at Village Hotel Changi, Singapore and Online.
Abstract
In
this keynote talk, it will be explored the use of the Hill model to assess the
Benchmark dose (BMD), the lethal dose 50 (LD50), the cooperativity (E) and the
dissociation constant (K) while analyzing cell viability data using nanomaterials.
The presentation is addressed to discuss the antitumor potential while
combining radiofrequency (RF) therapy in and selected nanomaterials. In
particular, it will be discussed the use of nanocomposites, for instance
comprising graphene oxide (GO) surface functionalized with polyethyleneimine
(PEI) and decorated with gold nanoparticles (GO-PEI-Au). Data collected from
the cell viability assays using different tumor cell lines (e.g. LLC-WRC-256
and B16-F10) will be presented and discussed. The findings will demonstrate
that while the tested nanocomposite (e.g. GO-PEI-Au) may be biocompatible
against different cancer cell lines in the absence of radiofrequency (nRF), the
application of radiofrequency (RF) enhances the cell toxicity by orders of magnitude,
pointing to prospective studies with the tested cell lines using tumor animal
models.
