So far, near-infrared (NIR) light responsive nanostructures have been well-defined in cancer nanomedicine. However, poor penetration and retention in tumors are the limiting factors. Here, we report the ultrahigh penetration and retention of carbanosilica (graphene quantum dots, GQDs embedded mesoporous silica) in solid tumors. After NIR light exposure, quick (0.5 h) emission from the tumor area is observed that is further retained up to a week (tested up to 10 days) with a single dose administration of nanohybrids. Emissive and photothermally active GQDs and porous silica shell (about 31% drug loading) make carbanosilica a promising nanotheranostic agent exhibiting 68.75% tumor shrinking compared to without NIR light exposure (34.48%). Generated heat (∼52 °C) alters the permeability of tumor enhancing the accumulation of nanotheranostics into the tumor environment. Successive tumor imaging ensures the prolonged follow-up of image guided tumor regression due to synergistic therapeutic effect of nanohybrids.

Breast cancer continues to present a major clinical hurdle, largely attributable to its aggressive metastatic behavior and the suboptimal efficacy of standard chemotherapeutic regimens. Cisplatin (CDDP) is a representative platinum drug in the treatment of breast cancer, however, its therapeutic application is often constrained by systemic toxicity and the frequent onset of chemoresistance. Here, we introduce a novel charge-adaptive nanoprodrug system, referred to as PP@, engineered to respond to tumor-specific conditions.

Background: Alzheimer's disease (AD) is increasingly recognized as a multifactorial disorder with vascular contributions, including a pro-coagulant state marked by fibrin deposition in the brain. Fibrin accumulation may exacerbate cerebral hypoperfusion and neuroinflammation, leading to neurodegeneration. Identifying patients with this pathology could enable targeted anticoagulant therapy.

This study focuses on the issues of poor fluidity, low penetration into residual coal, and suboptimal inhibition of coal spontaneous combustion associated with traditional coal mine gel fire retardants. The permeability and flow characteristics of a sodium alginate-based composite thermosensitive hydrogel, as well as its fire prevention and extinguishment performance, were investigated. The findings suggest that the thermosensitive hydrogel behaves as a pseudoplastic fluid at 40 °C and a yield-pseudoplastic fluid at 65 °C, exhibiting shear-thinning behavior with increasing shear rate.

Nanomedicine has shown remarkable promise in advancing tumor imaging and therapy through its ability to achieve targeted delivery, precision imaging, and therapeutic efficacy. However, translating these preclinical successes into clinical practice remains fraught with challenges, including inconsistent tumor targeting, off-target organ accumulation, and a lack of comprehensive understanding of in vivo behavior of nanomedicines. In this perspective, the current state of nanomedicine research is critically analyzed, emphasizing the translational bottlenecks and offering a forward-looking view on potential solutions.

Introduction: Workplace-related traumatic lip injuries, particularly at the vermilion-cutaneous junction, are challenging due to functional impairment and visible scarring. While typically managed in specialized settings, some cases present in primary care clinics. This report details the successful management of a penetrating laceration at this junction using layered closure and MEBO for optimized healing, with postoperative scar massage therapy to enhance recovery.
