Abstract
Cancer immunotherapy is an innovative treatment strategy to enhance the ability of the immune system to recognize and eliminate cancer cells. However, dose limitations, low response rates, and adverse immune events pose significant challenges. To address these limitations, gold nanoparticles (AuNPs) have been explored as immunotherapeutic drug carriers owing to their stability, surface versatility, and excellent optical properties. This review provides an overview of the advanced synthesis routes for AuNPs and their utilization as drug carriers to improve precision therapies. The review also emphasises various aspects of AuNP-based immunotherapy, including drug loading, targeting strategies, and drug release mechanisms. The application of AuNPs combined with cancer immunotherapy and their therapeutic efficacy are briefly discussed. Overall, we aimed to provide a recent understanding of the advances, challenges, and prospects of AuNPs for anticancer applications.

Abstract
Atherosclerosis is a global disease with an extremely high morbidity and fatality rate, so it is necessary to develop effective treatments to reduce its impact. In this work, we successfully prepared a multifunctional drug-loaded nano-delivery system with pH-responsive, CD44-targeted, and chemical-photothermal synergistic treatment. Dendritic mesoporous silica nanoparticles capped with copper sulfide (CuS) were synthesized via an oil-water biphase stratification reaction system; these served as the carrier material and encapsulated the anticoagulant drug heparin (Hep). The pH-sensitive Schiff base bond was used as a gatekeeper and targeting agent to modify hyaluronic acid (HA) on the surface of the nanocarrier. HA coating endowed the nanocomposite with the ability to respond to pH and target CD44-positive inflammatory macrophages. Based on this multifunctional nanocomposite, we achieved precise drug delivery, controlled drug release, and chemical-photothermal synergistic treatment of atherosclerosis. The in vitro drug release results showed that the nanocarriers exhibited excellent drug-controlled release properties, and could release drugs in the weakly acidic microenvironment of atherosclerotic inflammation. Cytotoxicity and cell uptake experiments indicated that nanocarriers had low cytotoxicity against RAW 264.7 cells. Modification of HA to nanocarriers can be effectively internalized by RAW 264.7 cells stimulated by lipopolysaccharide (LPS). Combining CuS photothermal treatment with anti-atherosclerosis chemotherapy showed better effects than single treatment in vitro and in vivo. In summary, our research proved that H-CuS@DMSN-NC-HA has broad application prospects in anti-atherosclerosis.
