Thrombus treatment faces great challenges because of the difficulties in the early diagnosis and prevention, and targeted thrombolytic therapy. As a result, there is an urgent need to explore unique strategies to achieve the multiple targets of diagnosis, treatment, and prevention (DTP) by integrating them into one nanosystem. Gold nanoparticles (AuNPs) as a classical type of inorganic nanomaterials with gold, is emergingly found effective in all stages of thrombus therapy due to the superiority of good optical properties, surface plasmon resonance, and biocompatibility. In this review, we focused on the multifunctional roles of AuNPs including visual diagnosis through optical imaging and biomarkers, thrombolytic therapy by photothermal effect and targeting delivery, and prevention of thrombosis in blood vessels and re-embolism of artificial im-plants. Especially, the application prospects of AuNPs and the optimization strategies of their nanocomposites are highlighted and discussed. It is anticipated to provide insight on the development of a more potential integrated platform for precise thrombus therapy.

Background: With the help of superparamagnetic iron oxide nanoparticles (SPIONs), cells can be magnetically directed so that they can be accumulated at target sites. This principle can be used to make monocytes magnetically steerable in order to improve tumor accumulation, e.g.

Background: Gynecological cancers are characterized by uncontrolled cell proliferation within the female reproductive organs. These cancers pose a significant threat to women's health, impacting life expectancy, quality of life, and fertility. Nanoparticles, with their small size, large surface area, and high permeability, have become a key focus in targeted cancer therapy.

In this study, we used two-dimensional electronic spectroscopy to examine the early femtosecond dynamics of suspensions of colloidal gold nanorods with different aspect ratios. In all samples, the signal distribution in the 2D maps at this timescale shows a distinctive dispersive behavior, which can be explained by the interference between the exciting field and the field produced on the nanoparticle's surface by the collective motion of electrons when the plasmon is excited. Studying this interference effect, which is active only until the plasmon has been dephased, allows for a direct estimation of the dephasing time of the plasmon of an ensemble of colloidal particles.

Triclosan (TCS) is used as an antibacterial agent in various products. One of the major issues associated with TCS is its limited solubility in aqueous media, which can reduce its effectiveness against bacteria. In this study, we enhanced the aqueous solubility and antibacterial activity of TCS by using a re-dispersible emulsion powder stabilized with gold nanoparticles (GNPs).

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.
