Abstract

The use of nanotechnology has been widely used in the last decade, emerging as a technological revolution that has presented a low-cost alternative with more effective action due to its nanometric size. The combination of nanotechnology and natural products from medicinal plants or fungi may be a new approach to seek to improve the treatment of some diseases. Additionally, considering the significant increase in multidrug-resistant bacteria, the World Health Organization published a list of bacteria that represent the greatest threat to human health, aiming to promote research into new antibiotics. In this context, natural products, a source of inspiration for obtaining new antibiotics, can be used in natura or can be combined with silver nanoparticles to enhance their antimicrobial potential. Thus, the project aims to evaluate natural products extracted from plants and fungi and their combinations with silver nanoparticles concerning their bactericidal potential, including against some multidrug-resistant strains, which may be a promising alternative to current drugs.
