Summary

This review evaluates the current state of nanoparticle safety research across medical, cosmetic, and industrial applications. Researchers found that despite two decades of progress, significant questions remain about the long-term effects of nanoparticle exposure, and the study calls for standardized testing methods and better understanding of how these tiny particles interact with biological systems.

The field of nanotechnology has grown over the last two decades and made the transition from the benchtop to applied technologies. Nanoscale-sized particles, or nanoparticles, have emerged as promising tools with broad applications in drug delivery, diagnostics, cosmetics and several other biological and non-biological areas. These advances lead to questions about nanoparticle safety. Despite considerable efforts to understand the toxicity and safety of these nanoparticles, many of these questions are not yet fully answered. Nevertheless, these efforts have identified several approaches to minimize and prevent nanoparticle toxicity to promote safer nanotechnology. This review summarizes our current knowledge on nanoparticles, their toxic effects, their interactions with mammalian cells and finally current approaches to minimizing their toxicity.

Current hurdles to the translation of nanomedicines from bench to the clinic

This review examines the challenges of translating nanomedicine research from the lab to approved medical treatments, focusing on regulatory hurdles and manufacturing consistency. While not directly about microplastics, the review is relevant because the same nanoparticle characterization methods and safety testing frameworks apply to understanding how nanoplastics behave in the human body. Lessons from nanomedicine development can help researchers better assess the health risks of nanoplastic exposure.
