The main concept of radiosensitization is making the tumor tissue more responsive to ionizing radiation, which leads an increase in potency radiation therapy and allows for decreasing dose concomitant side effects. Radiosensitization by metal oxide nanoparticles widely discussed, but range mechanisms studied not sufficiently codified often does reflect ability nanocarriers have a specific impact on cells. This review focused magnetic iron while they occupied special niche among prospective radiosensitizers due unique physicochemical characteristics reactivity. We collected data about possible molecular underlying radiosensitizing effects (IONPs) approaches their therapeutic efficacy variable modifications.

Abstract Notwithstanding immune checkpoint blocking (ICB) therapy has made eminent clinical breakthroughs, overcoming immunologically “cold” tumors remains challenging. Here, a cascade potentiated nanomodulator AuPtAg‐GOx is engineered for boosting responsiveness. Upon 1064 nm laser irradiation, AuPtAg‐mediated mild photothermal (PTT) activates cytotoxic T lymphocytes and reverses the immunogenic tumor microenvironment. Further, to amplify thermal sensitivity of cells, glucose oxidase (GOx) introduced suppress production heat shock proteins, thereby promoting therapy. Complementarily, AuPtAg nanozymes with catalase‐like activity can ameliorate hypoxia, significantly improving GOx activity. As result, combination self‐augmented ability PD‐L1 antibody further escalate antitumor efficacy. The AuPtAg‐GOx‐based synergistic starvation therapy, PTT, immunotherapy enhancement strategy be favorable tool effectively kill cancer cells.

Despite significant advances in cancer therapy over the years, its complex pathological process still represents a major health challenge when seeking effective treatment and improved healthcare. With advent of nanotechnologies, nanomedicine-based has been widely explored as promising technology able to handle requirements clinical sector. Superparamagnetic iron oxide nanoparticles (SPION) have at forefront nanotechnology development since mid-1990s, thanks their former role contrast agents for magnetic resonance imaging. Though use MRI probes discontinued due an unfavorable cost/benefit ratio, several innovative applications therapeutic tools prompted renewal interest. The unique characteristics SPION, i.e., properties enabling specific response submitted high frequency (magnetic hyperthermia) or low (magneto-mechanical therapy) alternating field, ability generate reactive oxygen species (either intrinsically activated using various stimuli), make them particularly adapted therapy.

Sonodynamic therapy (SDT) is a promising non-invasive therapeutic modality to treat deep-seated tumors owing the good tissue penetration ability and spatiotemporal controllability of ultrasound (US); however, low sonodynamic activity potential side effects greatly limit its clinical translation. Cancer immunotherapy that leverages immune system fight against cancer has great synergize with SDT for treatment high efficiency safety. In this review, convergence exert their merits break through limitations combination sono-immunotherapy are discussed.

The development of bacterial vaccines for inducing an immunoresponse against infectious diseases such as osteomyelitis is great significance and importance. However, the responsiveness immunotherapy remains far from being satisfactory, largely due to erratic antigen epitopes bacteria. Herein, we report in situ vaccination strategy infection based on model using a biomimetic nanomedicine named HMMP, which was constructed by engineering PpIX-encapsulated hollow MnOx with hybrid membrane exfoliated both macrophage tumor cell lines. as-established HMMP features burst release vaccine augmented sonodynamic treatment resultant priming antigen-presenting cells following activations cellular humoral adaptive immunities infections. This regimen not only triggers initial regression established but also simultaneously generates robust systemic antibacterial immunity poorly immunogenic secondary contralateral knee additionally confers long-lasting bacteria-specific immune memory responses prevent relapse. Thus, our study provides proof concept activation innate responses, providing individual-independent immunotherapy.

The complexity, diversity, and heterogeneity of malignant tumors pose a formidable challenge for antitumor therapy. To achieve the goal significantly enhancing effect, nanomedicine-based synergistic therapy is one important strategies. Herein, we innovatively report defect-rich glassy IrTe2 (G-IrTe2) with weak Ir–Te bond strength sonodynamic (SDT), chemodynamic (CDT), mild photothermal (PTT). G-IrTe2 sonosensitizer under ultrasound (US) stimuli exhibits excellent reactive oxygen species (ROS) production performance. Besides, catalase (CAT)-like activity can provide abundant to enhance SDT effect. Then, theoretical calculation verifies that US easily make irregular be broken in amorphous free electrons will released combine further form singlet (1O2). Meanwhile, peroxidase (POD)-like also catalyze endogenous H2O2 produce more ROS which conducive better tumor ablation. Furthermore, produced by sono-/chemodynamic processes cause mitochondrial dysfunction give rise heat shock protein (HSP) downregulated expression, maximizing efficiency PTT. Therefore, such rich defect could involved oncotherapy then effectively outstanding efficacy. This study provides new research idea expanding application inorganic nanomaterials promoting therapeutic effect tumors.

Although immunotherapy is relatively effective in treating hematological malignancies, their efficacy against solid tumors still suboptimal or even noneffective presently. Compared to cancers, exhibit strikingly different immunosuppressive microenvironment, severely deteriorating the of immunotherapy: (1) chemical features such as hypoxia and mild acidity suppress activity immune cells, (2) pro-tumorigenic domestication cells microenvironment within further undermines effectiveness immunotherapy, (3) dense physical barrier tumor tissues prevents intratumoral infiltration contact killing active cells. Therefore, we believe that reversing are critical priority for tumors. Due unique morphologies, structures, compositions, nanomedicines have become powerful tools achieving this goal. In Perspective, will first briefly introduce then summarize most recent progresses nanomedicine-based by remodeling immune-microenvironment a comprehensive manner. It highly expected Perspective aid advancing tumors, optimistic on future development burgeoning field.

Pancreatic cancer, with extremely limited treatment options and poor prognosis, urgently needs a breakthrough in early diagnosis monitoring. Tumor exosomes (T-Exos) detection is presently one of the most clinically significant liquid biopsy approaches for non-invasive pancreatic cancer diagnosis, which, unfortunately, cannot be applied as routine diagnostic tool until number obstacles, such unsatisfactory specificity sensitivity, well labor-intensive purification analysis procedures by ultracentrifugation enzyme-linked immunosorbent assay, are overcome. Here, we report facile nanoliquid assay especially specific, ultrasensitive yet economical T-Exos dual specific biomarker antigen co-recognition capturing strategy, which enabled grafting two corresponding capture antibodies on magnetic nanoparticles gold nanoparticles, accurate target tumor exosomes. This approach exhibits excellent ultrahigh sensitivity detecting low 78 pg/mL exosome protein GPC1. Successful screening 21 samples from 22 normal control cases enhanced ensures promising monitoring stage cancer.
