Biomagnetic fluid dynamics (BFD) is an emerging and promising field within fluid mechanics, focusing on the dynamics of bio-fluids like blood in the presence of magnetic fields. This research is crucial in the medical arena for applications such as medication delivery, diagnostic and therapeutic procedures, prevention of excessive bleeding, and treatment of malignant tumors using magnetic particles. This study delves into the intricacies of blood flow induced by cilia, carrying trihybrid nanoparticles (gold, copper, and titania), within a catheterized arterial annulus under a robust magnetic field.

Introduction: Monogenic diseases can be diagnosed before birth. Systemic fetal administration of nanoparticles (NPs) grants therapeutic access to developing stem cell populations impacted by these classes of disease. Delivery of editing reagents in these NPs administered before birth has yielded encouraging results in preclinical mouse models of monogenic diseases.

Decentralized testing using multiplex lateral flow assays (mLFAs) to simultaneously detect multiple analytes can significantly enhance detection efficiency, reduce cost and time, and improve analytic accuracy. However, the challenges, including the monochromatic color of probe particles, interference between different test lines, and reduced specificity and sensitivity, severely hinder mLFAs from wide use. In this study, we prepared polydopamine (PDA)-coated dyed cellulose nanoparticles (dCNPs@P) with tunable colors as the probe for mLFAs.

Dyes can seriously harm human health because they linger or break down in the environment and find their way into drinking water through the water cycle. Examples of the most important interactions between MOFs and dyes are provided, and an effort is made to comprehend how surface charge and size compatibility affect the adsorption process. The methods for incorporating functionalized Ce-MOF into electrospun nanofibers made of polyvinyl alcohol and chitosan to create functionalized cerium metal organic framework nanofiber membranes (FCCP nanofiber membranes) are presented in this paper.

The large recruitment of tumor-associated macrophages and low exposure of tumor-associated antigens in tumor microenvironment have severely suppress the efficacy of anti-tumor immunotherapy. Herein, biosynthesized magnetosome (Mag) from bacteria was loaded with photothermal/photodynamic agent/near infrared (NIR) fluorescence dye (IR780) and further modified with lipid-PEG-c(RGDyK) through biomembrane, forming Mag for fluorescence imaging, magnetic resonance imaging, immunotherapy and photodynamic/photothermal therapy. After intravenous injection into B16F10 tumor-bearing mice, Mag could efficiently accumulate in tumor tissues based on near infrared (NIR) fluorescence and magnetic resonance dual-modality imaging, and repolarize tumor-associated macrophages (TAMs) from M2 phenotype to M1 phenotype, significantly improving the effect of tumor immunotherapy.
