Special Issue Information

Dear Colleagues,

Polymer nanomaterials play a vital role in biomedicine because of their following characteristics: improved targeting, reduced side effects, and excellent biocompatibility. To realize the diagnosis and treatment of diseases, polymer nanomaterials can load diagnostic reagents and drugs via chemical conjugation and physical encapsulation. In addition, these nanomaterials can be synthesized from polymers that possess theranostic capabilities on their own.

This Special Issue aims to cover the recent progress in and insights into polymer nanomaterials for disease imaging and treatment. Original research articles and reviews are welcome. The research areas may include (but are not limited to) the following: (1) novel polymer nanomaterials for drug delivery; (2) the synthesis of functional polymers for disease imaging and therapy; and (3) polymer drug delivery systems for combination therapy.

I look forward to receiving your contributions.

Atherosclerosis (AS) is an important causative agent of cardiovascular diseases, and the occurrence and development of AS is accompanied by oxidative stress, so antioxidant therapy has become one of the strategies for the treatment of AS. This study aimed to design and construct an apolipoprotein ApoA1-modified inorganic–organic composite nanosystem for AS therapy, in which ApoA1 was modified onto carboxylated CeO2/Mn3O4 by covalent bonding, resulting in an inorganic–organic nanocomplex with a structure similar to that of high-density lipoprotein. The nanocomplex could effectively deliver the antioxidant nanoparticles to the AS plaque through the specific recognition between ApoA1 and the macrophage at the AS lesion site. For one thing, the nanocomplex could alleviate the oxidative stress environment of the AS site through the highly efficient antioxidant effect of CeO2/Mn3O4, which played a therapeutic role in the treatment of AS. For another, it could effectively eliminate the formed lipid plaques and maximally alleviate and treat AS by utilizing the cholesterol efflux effect of ApoA1. Full article

Hypoxic tumors pose considerable obstacles to cancer treatment, as diminished oxygen levels can impair drug effectiveness and heighten therapeutic resistance. Oral cancer, a prevalent malignancy, encounters specific challenges owing to its intricate anatomical structure and the technical difficulties in achieving complete resection, thereby often restricting treatment efficacy. The impact of hypoxia is particularly critical in influencing both the treatment response and prognosis of oral cancers. This article summarizes and examines the potential of polymer nanomedicines to address these challenges. By engineering nanomedicines that specifically react to the hypoxic tumor microenvironment, these pharmaceuticals can markedly enhance targeting precision and therapeutic effectiveness. Polymer nanomedicines enhance therapeutic efficacy while reducing side effects by hypoxia-targeted accumulation. The article emphasizes that these nanomedicines can overcome the drug resistance frequently observed in hypoxic tumors by improving the delivery and bioavailability of anticancer agents. Furthermore, this review elucidates the design and application of polymer nanomedicines for treating hypoxic tumors, highlighting their transformative potential in cancer therapy. Finally, this article gives an outlook on stimuli-responsive polymeric nanomedicines in the treatment of oral cancer. Full article
