Summary: Worldwide development and application of nanotechnology have led to significant scientific advancements. It is important to balance the high expectations and concerns associated with this field. Nanomedicine, a specific arm of nanotechnology, focuses on the diagnosis, treatment, and monitoring of various diseases. However, the concept of nanotoxicology has also emerged as a crucial aspect of nanomedicine. More research is needed to identify potential adverse effects and ensure the safety of nanomedicines.

Summary: We used vibrational sum-frequency generation spectroscopy to study the effect of isotopic substitution on the properties of a DPPC monolayer. We found that deuteration of the choline group significantly impacted the monolayer properties, while deuteration of the alkyl chains did not have any effect. Deuteration of the choline group also affected the hydration of the phosphate group.

Summary: This review discusses the role, physicochemical properties, potential applications, and toxicological effects of magnetic nanoparticles (MNPs) in complex biological systems. MNPs have been widely used in various industries, leading to increased interactions with biological organisms. However, the full impact of these particles on complex biological systems and the toxicology aspects of their biomedical applications remain unclear, with mixed and inconclusive results. A consolidative framework that considers the physicochemical properties and potential risks of MNPs is necessary for their future manageable applications.

Summary: The research investigates the adsorption process of magnetite nanoparticles functionalized with aminated chitosan into cell membrane models. The study demonstrates a membrane model composition-dependent regulation of phospholipid-nanoparticle interactions, with stronger adsorption of Fe3O4-AChit nanoparticles into negatively charged DPPG monolayers likely due to electrostatic attraction. Additionally, differences in adsorption strength of the nanoparticles into Langmuir films formed by phosphatidylcholines were observed, with easier adsorption into more loosely packed POPC monolayers.

Summary: This study suggests that the traditional route-to-route extrapolation approaches for PBPK modeling of small molecules are not applicable to NPs. Therefore, multi-route PBPK models for NPs should be developed using route-specific data. The PBPK model using the new approach showed superior performance compared to the traditional approach. In addition, QSAR-based multivariate linear regressions were established to predict key biodistribution parameters based on the physicochemical properties of AuNPs.

Summary: This study investigated the effects of graphene oxide (GO) and reduced graphene oxide (rGO) on zebrafish hepatocytes using in vitro assays. The results showed that the internalization of GO increased with increasing concentrations, while rGO had stronger interaction with the cell membrane due to its hydrophobic characteristic. After 72 hours of exposure, both GO and rGO showed harmful effects on the cells, but with different mechanisms of toxicity.

Summary: The study highlights the development of a nanoparticle-based synthetic mitochondrial transcription regulator (MitoScript) for controlling mitochondrial DNA transcription. MitoScript demonstrates great colloidal stability, biocompatibility, efficient cell uptake, and selective mitochondria targeting. It effectively downregulated the expression of the ND6 gene, which impacted the cell's redox status, resulting in increased ROS generation. This technology could contribute to understanding mitochondrial disorders and developing treatments for mitochondrial diseases.

Summary: Degeneration of fibrocartilaginous tissues is often associated with complex pro-inflammatory factors, including reactive oxygen species (ROS), cell-free nucleic acids (cf-NAs), and epigenetic changes in immune cells. A self-therapeutic and epigenetic modulator-encapsulated hybrid protein nanoscaffold shows promise for restoring dysregulated inflammatory signaling and treating degenerative fibrocartilaginous diseases, such as disc injuries. The nanoscaffold exhibits inflammatory stimuli-responsive drug release, disc-mimetic stiffness, and excellent biodegradability, along with the ability to scavenge ROS and cf-NAs, reducing inflammation and promoting tissue regeneration.

Summary: Nanotechnology offers a promising approach for targeted drug delivery, improving the effectiveness and safety of therapeutics. Nanomaterials developed for selective targeting of cancers can potentially treat off-target effects caused by chemotherapy. Chemotherapy-induced neurotoxicity, neuropathy, and cardiomyopathy are common side effects that impact the quality of life for breast and ovarian cancer survivors. Nanoparticles have the potential to enhance therapeutic efficacy and reduce side effects, but more research is needed to develop interventions for women cancer survivors.

Summary: Intervertebral disc degeneration is a common cause of back pain and can lead to more serious conditions such as disc herniation and spinal stenosis. Traditional growth factor therapies have limited effectiveness in completely regenerating degenerated discs, thus there is a need for bioscaffolds. A new injectable bioorthogonal hydrogel, called BIOGEL, was developed using tetrazine-norbornene bioorthogonal ligation combined with gelatin. This BIOGEL showed promising results in promoting tissue repair and functional recovery in rat models of IVD degeneration.
