Abstract
Water-soluble polymers have been used in the last two decades to modify the pharmacokinetics and physicochemical properties of targeted therapeutic agents. Non-invasive imaging techniques such as nuclear imaging can be used to assess the drug delivery efficiency of novel formulations in a cost-effective fashion and thereby facilitate their development process. Polymeric radiopharmaceuticals have also been investigated on their own right as potential nuclear imaging agents. Clinical applications of polymeric radiopharmaceuticals include blood-pool imaging and targeted molecular imaging. In the latter case, water-soluble polymers are often used to modify the pharmacokinetics and biodistribution pattern of ligands that target receptors or antigens at disease sites. As advances are continue to be made in the emerging field of molecular imaging, nuclear imaging will play an increasingly important role in the development of polymeric drug delivery systems. Similarly, polymer technology will also be integrated into the development of molecularly targeted radiopharmaceuticals. Here, we review various aspects of polymeric radiotracers and their applications in nuclear imaging.

Advances of natural products, bio-actives and novel drug delivery system against emerging viral infections
Due to the increasing prevalence of viral infections and the ability of these human pathogens to develop resistance to current treatment strategies, there is a great need to find and develop new compounds to combat them. These molecules must have low toxicity, specific activity and high bioavailability. The most suitable ...read more
Electrospun Fibers as Drug Delivery Systems
In recent years, electrospun fibers have attracted considerable attention as potential platforms for drug delivery due to their distinctive properties and adaptability. These fibers feature a notable surface area-to-volume ratio and can be intentionally designed with high porosity, facilitating an increased capacity for drug loading and rendering them suitable for ...read more
Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
