Summary: We synthesized magnetic IONP/polymer nanocomposites (MNCs) by embedding IONPs in a poly(L-lactic acid) (PLA) matrix via nanoemulsion. The MNCs showed enhanced heating efficiency with over two-fold increase compared to nonembedded bare IONPs. In addition, the MNCs exhibited good colloidal stability under physiological conditions and maintained their heating efficiency during 48 h of incubation in cell culture medium.

Summary: One of the main reasons for chemotherapy resistance in cancer patients is inadequate drug accumulation in tumors. To address this issue, a highly efficient tumor-targeted and stroma-breaking nanocarrier, c(RGDyK)-HAase-IONP, was developed. This nanocomplex effectively targeted tumors by binding to integrin alpha v beta 3 and penetrated deep into tumors by degrading hyaluronic acid (HA) in the tumor extracellular matrix (ECM). In vivo studies demonstrated improved tumor targeting and significant inhibition of tumor growth using c(RGDyK)-HAase-IONP/DOX.

Summary: A rapid and sensitive approach for the detection of endopeptidases, utilizing the AMELIE mechanism, has been developed. The AMELIE mechanism involves the mutual enzymatic activity of immobilized enzymes triggered by the target endopeptidase analyte. The proof of concept demonstrated the detection of collagenase with a detection limit of 2.5 pg/mL and a wide linear range. The AMELIE biosensor has the potential for the sensitive detection of other endopeptidases.

Summary: The co-occurrence of nanoplastics with metal oxide nanoparticles and polycyclic aromatic hydrocarbons has been widely studied, yet little is known about their interactions and combined toxic effects. This research found that increasing the concentration of metal oxide nanoparticles led to aggregation of nanoplastics, while polycyclic aromatic hydrocarbons had no major impact on nanoplastic stability. The size of the nanoplastics played a role in genotoxicity, with smaller nanoplastics showing higher levels of DNA damage.

Summary: One of the biggest challenges in surgical procedures is the closing and healing of wounds, which are crucial in orthopedics, trauma, intensive care, and general surgery. Chronic wounds, especially in immunosuppressant or diabetic patients, have been linked to a high fatality rate. Due to the insufficiency of current therapeutic methods, there is a need for innovative techniques in wound healing. Nanomaterial-based therapeutics have emerged as alternative solutions for effective wound healing. This review provides an overview of wound infections, the wound healing process, conventional therapies, and explores the advances in nanotechnological approaches for wound healing using various nanomaterials.

Summary: This study developed an immunochromatographic (ICG) strip for the detection of Salmonella using in-house generated antibodies conjugated with gold nanoparticles. The strip was integrated with a colorimetric method and the ColorGrab application on a smartphone. The developed diagnostic platform showed the ability to detect Salmonella in a linear range of 107-100 CFU/mL, and the results were further confirmed by the smartphone-based ColorGrab application. The ICG strips were validated with spiked fecal, meat, and milk samples, providing results in 10 minutes and remaining stable for 28 days at 4°C and 37°C. Therefore, the in-house fabricated ICG strip can be utilized as a portable and cost-effective diagnostic device for rapid detection of Salmonella strains in food samples.
