Abstract Accumulation at tumor tissue without any damage to healthy normal tissues is an ultimate goal in cancer therapy. Despite many efforts in the field of cancer therapy, this disease remains as the major reason of mortality all over the world. Gene therapy has introduced great opportunity to fight against cancer disease. It should be noted that still some obstacles limit clinical application of gene delivery approach, which have to be overcome for efficient transportation of therapeutic gen...

Abstract We propose the use of an implantable device with multiple embedded drug diffusion channels, each of which is connected to a drug reservoir, for the controlled release of diclofenac. To minimize the size of the incision needed during device implantation, the device used herein was made of the soft biocompatible material polydimethylsiloxane (PDMS), thereby allowing for folding during device implantation. We aimed to achieve a profile of diclofenac release that was reproducible even after...

Abstract Liraglutide is a GLP-1 receptor agonist recently approved for Type-II diabetes (T2D) treatment with superior hypoglycemic effect while also improving cardiovascular function for the patients. However, its application has been limited by its short half-life (~13 h), which requires daily injections to maintain effective drug concentrations in blood, thus increasing the risk of poor patient compliance and complications. In this study, we developed a ternary liraglutide/tannic acid (TA)/Al3...

Abstract Embolization therapy is an attractive strategy for antitumor therapy, especially for solid tumors. In vivo self-coagulation behavior holds great potential in a new type of tumor embolization therapy. However, spatiotemporal controllable in situ formation of thrombus in tumor is a challenge. Herein, an ultrasound (US)-responsive ultra-sensitive “thrombus constructor” (UUNC), which was prepared by loading thrombin into a nanobubble, and modified with NGR peptide on its surface, is rationa...

Abstract Targeted drug delivery to diseased vasculature, such as atherosclerotic lesions, is a multistep process, which is based on the transport of drug carriers to a selected region and their deposition at the desired destination. Current modeling approaches, including microfluidics and animal models, fail to accurately simulate this multi-scale process in human arteries, where blood flow is dominant. Here we study particle deposition in endothelialized 3D reconstructed models of the human car...

Abstract Quantum dots offer superior optical features and hold a great potential as an imaging tool in comparison to ‘conventional’ fluorescent dyes. However, in vivo application in inflammatory-associated disorders is limited due to potential toxicity following systemic administration. Vascular inflammation contributes to cardiovascular diseases such as restenosis (re-narrowing of the artery following angioplasty), and poor prognosis is associated with the increased number of monocytes-derived ...

Abstract Black phosphorus nanosheets (BP NSs), a kind of attractive two-dimensional materials, have been widely used in optoelectronics, transistors and photocatalysis. Recently, growing interest has been attracted to explore the application of BP NSs for cancer therapy in view of their unique properties. BP NSs have high surface area and negative charge, which can load drug, targeting molecules, photosensitizer, magnetic nanoparticles etc. They are also potential candidates for cancer photother...

Abstract Targeted drug delivery to joint tissues like cartilage remains a challenge that has prevented clinical translation of promising osteoarthritis (OA) drugs. Local intra-articular (IA) injections of drugs suffer from rapid clearance from the joint space and slow diffusive transport through the dense, avascular cartilage matrix comprised of negatively charged glycosaminoglycans (GAGs). Here we apply drug carriers that leverage electrostatic interactions with the tissue's high negative fixed...

Abstract Hydrogels for biomedical applications such as controlled drug release are usually synthesized with the chemical or physical crosslinking of monomers or macromers. In this work, we used gelatin to prepare hydrogel nanoparticles and studied whether gelatin nanoparticles (GNPs) could assemble to form a solid biomaterial and whether this solid biomaterial was capable of transforming into a hydrogel upon introduction to a hydrated environment. The data show that GNPs with or without aptamer ...

Abstract Filomicelles possess some unique properties for improved in vivo drug delivery efficiency relative to commonly used spherical nanocarriers, which have attracted great interests. However, the length effect of the block copolymer prodrug-based filomicelles with a comparable cross-section diameter on the drug delivery efficiency and antitumor efficacy still need to be systematically studied. In this report, we prepare three optimized nanoparticles with a comparable cross-section diameter o...
