Three-dimensional (3D) liver cell models - a tool for bridging the gap between animal studies and clinical trials when screening liver accumulation and toxicity of nanobiomaterials

Melissa Anne Tutty et al.

Summary: Despite the wide applications of nanobiomaterials (NBMs) in human health, their translation from lab to clinic is slow due to liver accumulation and toxicity. The commonly used in vitro and in vivo methods are insufficient in predicting NBM hepatotoxicity, posing a significant challenge. This review discusses the relationship between NBMs and the liver, limitations of toxicity assessment methods, recent advancements in tissue-mimetic 3D cell models, and the low public acceptance and limited uptake of these models.

Physiologically based pharmacokinetic modeling of intravenously administered nanoformulated substances

Jordi Minnema et al.

Summary: The use of nanobiomaterials in medicine is gaining popularity. This study implemented and parametrized a physiologically based pharmacokinetic (PBPK) model to better understand the biodistribution of two nanobiomaterials in rats. The results showed significant kinetic differences between the two materials, highlighting the need for tailored parametrization of PBPK models. These findings contribute to the establishment of a comprehensive database for predictive biodistribution modeling.

Evaluating nanobiomaterial-induced DNA strand breaks using the alkaline comet assay

Melissa Anne Tutty et al.

Summary: Due to their unique properties, nanobiomaterials are extensively studied for medical and drug delivery applications. However, their small size also makes them susceptible to toxicity. While the immunotoxicity and cytotoxicity of nanomaterials have been well studied, there is limited data on their genotoxicity or ability to cause DNA damage. In recent years, there has been increased attention to genotoxicity screening of nanomaterials due to new medical device regulations. Through an interlaboratory comparison study, the alkaline comet assay was found to be a suitable method for assessing nanobiomaterial-induced DNA damage.

Standardization of an in vitro assay matrix to assess cytotoxicity of organic nanocarriers: a pilot interlaboratory comparison

Kai Moritz Eder et al.

Summary: This study confirmed the suitability and reproducibility of a cytotoxicity matrix consisting of two endpoints performed with four cell lines across three partner laboratories. The experiments showed that Liplmage (TM) 815 lipidots (R) were non-cytotoxic up to a concentration of 128 μg/mL, while poly(alkyl cyanoacrylate) (PACA) nanoparticles for drug delivery had dose-dependent cytotoxic effects on cell lines starting from 8 μg/mL. These findings provide valuable information for the development of organic nanomaterials used in medicine.
