## Abstract

Biogenic nanoparticles are distinguished by their unique physical and chemical attributes, notably their potent antimicrobial activity against bacterial and fungal pathogens, as well as their cytotoxic effects on cancer cells. These nanoparticles are characterized by their biocompatibility, indicating their potential as effective antimicrobial agents and in oncological therapies. This article examines the existing literature on the antimicrobial and cytotoxic properties of nanoparticles derived from cyanobacteria, with particular emphasis on their implications for human health.

The article reviews the green synthesis of biogenic nanoparticles produced by cyanobacteria, highlighting their antimicrobial and cytotoxic properties. These nanoparticles, formed intra‐ or extracellularly, show activity against Gram‐positive and Gram‐negative bacteria as well as fungi and can induce apoptosis in tumor cells. With biocompatibility and structural diversity, they emerge as promising alternatives in biotechnology and cancer therapies.© 2026 WILEY‐VCH GmbH
