Nanoparticles (NPs) play a key role in nanomedicine in multimodal imaging, drug delivery and targeted therapy of human diseases. Consequently, due to the attractive properties of NPs including high stability, high payload, multifunctionality, design flexibility, and efficient delivery to target tissues, nanomedicine employs various types of NPs to enhance targeting and treatment efficacy. In this review, we primarily focus on light-responsive materials, such as fluorophores, photosensitizers, semiconducting polymers, carbon structures, gold particles, quantum dots, and upconversion crystals, for their biomedical applications...

Cardiovascular diseases are the leading cause of death worldwide. Despite preventive efforts, early detection of atherosclerosis, the common pathophysiological mechanism underlying cardiovascular diseases remains elusive, and overt coronary artery disease or myocardial infarction is often the first clinical manifestation. Nanoparticles represent a novel strategy for prevention, diagnosis, and treatment of atherosclerosis, and new multifunctional nanoparticles with combined diagnostic and therapeutic capacities hold the promise for theranostic approaches to this disease...

The nonradiative conversion of light energy into heat (photothermal therapy, PTT) or sound energy (photoacoustic imaging, PAI) has been intensively investigated for the treatment and diagnosis of cancer, respectively. By taking advantage of nanocarriers, both imaging and therapeutic functions together with enhanced tumour accumulation have been thoroughly studied to improve the pre-clinical efficiency of PAI and PTT. In this review, we first summarize the development of inorganic and organic nano photothermal transduction agents (PTAs) and strategies for improving the PTT outcomes, including applying appropriate laser dosage, guiding the treatment via imaging techniques, developing PTAs with absorption in the second NIR window, increasing photothermal conversion efficiency (PCE), and also increasing the accumulation of PTAs in tumours...

Materials for the treatment of cancer have been studied comprehensively over the past few decades. Among the various kinds of biomaterials, polymer-based nanomaterials represent one of the most interesting research directions in nanomedicine because their controlled synthesis and tailored designs make it possible to obtain nanostructures with biomimetic features and outstanding biocompatibility. Understanding the chemical and physical mechanisms behind the cascading stimuli-responsiveness of smart polymers is fundamental for the design of multifunctional nanomaterials to be used as photothermal agents for targeted polytherapy...

In this review, we focus on recent advances in the synthesis of polymer-functionalized transition-metal-based nanomaterials and follow this up by discussing their applications in bioimaging diagnosis and cancer therapy. Transition-metal-based nanomaterials show great potential in cancer therapy owing to their intensive near-IR absorption, excellent photothermal conversion efficiency, strong X-ray attenuation, and magnetic properties. Functional polymers are usually introduced by a one-step or multistep method to further endow these nanomaterials with great biocompatibility and physiological stability...

Gold nanoparticles (AuNPs) have been extensively studied within biomedicine due to their biocompatibility and low toxicity. In particular, AuNPs have been widely used to deliver photosensitiser agents for photodynamic therapy (PDT) of cancer. Here we review the state-of-the-art for the functionalisation of the gold nanoparticle surface with both photosensitisers and targeting ligands for the active targeting of cancer cell surface receptors. From the initial use of the AuNPs as a simple carrier of the photosensitiser for PDT, the field has significantly advanced to include: the use of PEGylated modification to provide aqueous compatibility and stealth properties for in vivo use; gold metal-surface enhanced singlet oxygen generation; functionalisation of the AuNP surface with biological ligands to specifically target over-expressed receptors on the surface of cancer cells and; the creation of nanorods and nanostars to enable combined PDT and photothermal therapies...

Tumor therapeutic efficacy is determined, to a great extent, by the delivery efficiency of therapeutic drugs to their final targets. The cell nucleus has been proven to be the main interaction site for most therapeutic agents such as anticancer drugs, genes, free radicals, and heat. Therefore, it is highly expected that cell nucleus-targeting or nuclear membrane-penetrating nanotherapeutics would provide a more effective strategy than ordinary cell membrane-targeting ones for benefiting precise nanomedicine in humans' battles against cancer...

This review outlines recently developed Prussian blue nanoparticle (PB NPs)-based multimodal imaging-guided chemo-photothermal strategies for cancer diagnosis and treatment in order to provide insight into the future of the field. The primary limitation of existing therapeutics is the lack of selectivity in drug delivery: they target healthy and cancerous cells alike. In this paper, we provide a thorough review of diverse synthetic and surface engineering techniques for PB NP fabrication. We have elucidated the various targeting approaches employed to deliver the therapeutic and imaging ligands into the tumor area, and outlined methods for enhancement of the tumor ablative ability of the NPS, including several important combinatorial approaches...

Graphene family nanomaterials' (GFN) ability to interact with near-infrared light has propelled their application in cancer photothermal therapy. Furthermore, the graphitic lattice of GFN can adsorb different types of molecules, which has motivated their use in cancer drug delivery. However, the direct application of GFN in cancer therapy is severely hindered by their poor colloidal stability, sub-optimal safety, inefficient tumor uptake and non-selectivity towards cancer cells. To overcome these limitations, GFN have been functionalized with different types of materials...

Glucose oxidase (GOx) is an endogenous oxido-reductase that is widely distributed in living organisms. Over recent years, GOx has attracted increasing interest in the biomedical field due to its inherent biocompatibility, non-toxicity, and unique catalysis against β-d-glucose. GOx efficiently catalyzes the oxidization of glucose into gluconic acid and hydrogen peroxide (H2O2), which can be employed by various biosensors for the detection of cancer biomarkers. Various cancer therapeutic strategies have also been developed based on the catalytic chemistry of GOx: (1) the consumption of glucose provides an alternative strategy for cancer-starvation therapy; (2) the consumption of oxygen increases tumor hypoxia, which can be harnessed for hypoxia-activated therapy; (3) the generation of gluconic acid enhances the acidity of the tumor microenvironment, which can trigger pH-responsive drug release; (4) the generation of H2O2 increases the levels of tumor oxidative stress, and the H2O2 can be converted into toxic hydroxyl radicals that can kill cancer cells upon exposure to light irradiation or via the Fenton reaction...

Nanoparticle-based phototherapies, such as photothermal therapy (PTT) and photodynamic therapy (PDT), exhibit strong efficacy, minimal invasion and negligible side effects in tumor treatment. These phototherapies have received considerable attention and been extensively studied in recent years. In addition to directly killing tumor cells through heat and reactive oxygen species, PTT and PDT can also induce various antitumor effects. In particular, the resultant massive tumor cell death after PTT and PDT triggers immune responses, including the redistribution and activation of immune effector cells, the expression and secretion of cytokines and the transformation of memory T lymphocytes...
