Article Abstract
Nanosystems that deliver drugs have revolutionized modern therapy the accurate targeting and controlled release of drugs. The importance of real-time monitoring of these systems lies in the evaluation of their pharmacokinetics and biodistribution, as well as preventative treatment efficacy. Imaging methods thus gave birth to real-time monitoring, allowing visualization of nanoparticles (NPs) inside biological systems. This review introduces current imaging techniques such as optical imaging, computed tomography (CT), magnetic resonance imaging (MRI), nuclear imaging, ultrasound, and finally, hybrid techniques that are on the verge of being used. The principles, merits, demerits, and applications of each modality in tracking nanodrug delivery are summarized. Special importance is given to multimodal imaging based on the fact that it can help to overcome the limitations of any individual imaging modality, thereby offering better insight into drug delivery. Advances in imaging probes and imaging-guided drug delivery systems are illustrated to show this transformation of imaging in nanomedicine.

This study investigates a multifunctional hydrogel system integrating carboxymethyl cellulose (CMC) in a 3D-printed limonene (LIM) scaffold coated with poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS). The system allows to enhance wound healing, prevent infections, and monitor the healing progress. CMC is crosslinked with citric acid (CA) to form the hydrogel matrix (CMC-CA), while the 3D-printed limonene (LIM) scaffold is embedded within the hydrogel to provide mechanical support.

Persistent bacterial infections remain a major challenge in wound management. Although drug-loaded wound dressings have gained increasing attention, their therapeutic efficacy is often hindered by uncontrolled drug release and a lack of electrical signal responsiveness. Herein, an antibacterial dressing (CCS-PC) with electroactivity and stimulus-responsive drug release properties was fabricated via electro-assembly, wherein chitosan and ciprofloxacin hydrochloride (CIP) were co-deposited onto polypyrrole (PPy)-coated gauze.

Triple-negative breast cancer (TNBC) remains a formidable clinical challenge due to its aggressive behavior, lack of therapeutic targets, and poor prognosis. The PI3K/AKT/mTOR pathway is highly activated in TNBC, making it a promising therapeutic target. Conventional PEGylated nanocarriers often face challenges, such as accelerated blood clearance and lysosomal trapping.

Covalent organic frameworks (COFs) have been emerging as versatile reticular materials due to their tunable structures and functionalities, enabled by precise molecular engineering at the atomic level. While the integration of multiple components into COFs has substantially expanded their structural complexity, the strategic engineering of diverse functionalities within a single framework the random distribution of linkers with varying lengths remains largely unexplored. Here, we report a series of highly crystalline mixed-length multivariate COFs synthesized using azobenzene and bipyridine as linkers, where tuning the ratio of linkers and incorporating palladium effectively modulates the balance between near-infrared (NIR) light absorption and catalytic sites for NIR-generation of hydrogen peroxide (HO).
