Abstract Immunotherapy has received widespread attention for its effective and long‐term tumor‐eliminating ability. However, immunogenic “cold” tumors, such as prostate cancer (PCa), the low immunogenicity of tumor itself is a serious obstacle to efficacy. Here, this work reports strategy enhance PCa by triggering cascade self‐enhanced ferroptosis in cells, turning from “hot”. This develops transformable self‐assembled peptide TEP‐FFG‐CRApY with alkaline phosphatase (ALP) responsiveness...

Prostate cancer (PCa) is a frustrating immunogenic "cold" tumor and generally receives unsatisfied immunotherapy outcomes in the clinic. Pyroptosis an excellent cell death form that can effectively activate antitumor immune response, promote cytotoxic T-lymphocyte infiltration, convert tumors from to "hot." However, vivo application of pyroptosis drugs seriously limited, upregulation PD-L1 caused by photo-immunotherapy further promotes escape. Herein, new nano-photosensitizer (YBS-BMS...

Herein, a method was developed for the sensitive monitoring of carcinoembryonic antigen (CEA) by gold nanoparticles dotted prussian blue@polyaniline core-shell nanocubes (Au NPs/PB@PANI). First, facile low-temperature used to prepare uniform PB@PANI with assistance PVP, where PB acted as electron transfer mediator provide electrochemical signals, and PANI excellent conductivity desirable chemical stability not only played role protective layer prevent etching in basic media but also...

The development of a specifically sensitive approach for CA15-3 detection is great significance the early diagnosis and treatment monitoring breast cancer. In present work, an electrochemiluminescence (ECL) immunosensor was constructed selective based on dual-quenching strategy. Ru(dcbpy)32+, poly(ethylenimine) (PEI), gold nanoparticles (AuNPs) were immobilized dendritic mesoporous silica (DMSNs) (Ru-PEI/AuNPs@DMSNs) with high ECL efficiency due to loading amounts shortened electron-transfer...

Prostate cancer presents as a challenging disease, it is often characterized an immunologically "cold" tumor, leading to suboptimal outcomes with current immunotherapeutic approaches in clinical settings. Photodynamic therapy (PDT) harnesses reactive oxygen species generated by photosensitizers (PSs) disrupt the intracellular redox equilibrium. This process induces DNA damage both mitochondria and nucleus, activating of immunogenic cell death (ICD) cGAS-STING pathway. Ultimately, this...

In this work, we have developed a novel visual Hg2+ sensor in aqueous solution using unmodified Au@Ag core–shell nanoparticles at room temperature, based on redox reaction between Ag-shell and Hg2+. The prepared exhibited good monodispersity. the presence of Hg2+, was reduced into Hg (0) by Ag-shell, deposited surface Au-core to form Au–Hg alloys caused aggregation, leading color changes from yellow purplish red, plasmon resonance spectra red shift. Under optimal conditions, could...

A simple, sensitive, and fluorescent immunoassay for the detection of prostate-specific antigen (PSA) based on horseradish peroxidase silicon dioxide nanospheres as a signal amplification strategy has been described. In design, primary antibody (Ab1) PSA was first immobilized 96-well plates via physical adsorption between polystyrene hydrophobic groups molecule. The (SiO2 NSs), with large surface area good biocompatibility, were loaded (HRP) peroxidase-labeled secondary antibodies (HRP-Ab2)...

This work reports the first study on detection of dobutamine (DBTM) using magnesium oxide microflowers–nafion composite. Owing to large surface area and strong adsorption ability, composite exhibits excellent electrocatalytic activity toward DBTM, revealing a linear range 1.0–30 μM with limit 0.092 (3σ method).
