INTRODUCTION

The field of drug delivery has witnessed remarkable advancements in recent years, largely propelled by the development of functional nanomaterials. These nanomaterials, with dimensions at the nanoscale and tailored properties, have revolutionized the way therapeutic agents are administered, distributed, and released within the body. By harnessing the unique physicochemical properties of nanomaterials, researchers have created innovative drug delivery platforms capable of overcoming longstanding challenges in pharmacotherapy [1,2]. Functional nanomaterials offer several key advantages over conventional drug delivery systems. Firstly, their small size allows for enhanced bioavailability, prolonged circulation time, and improved cellular uptake. Additionally, nanomaterials can be engineered to respond to specific biological cues or stimuli, enabling controlled release of therapeutic payloads at the desired site of action [3-6]. Moreover, the surface of nanomaterials can be functionalized with targeting ligands, such as antibodies or peptides, to achieve precise targeting of diseased tissues or cells while minimizing off-target effects. In this review, we explore the contemporary progress in functional nanomaterials for drug delivery platforms. We examine the design principles, synthesis methods, and characterization techniques employed in the development of these nanomaterials. Furthermore, we highlight the diverse applications of functional nanomaterials in drug delivery, including targeted cancer therapy, treatment of infectious diseases, and management of chronic conditions. Despite the significant advancements made in the field, several challenges remain to be addressed [7,8]. These include concerns related to biocompatibility, scalability, and regulatory approval of nanomaterial-based drug delivery systems. Additionally, the translation of nanomedicines from bench to bedside requires rigorous preclinical and clinical evaluation to ensure safety and efficacy. The field of drug delivery has witnessed significant advancements driven by the development of functional nanomaterials [9,10]. These nanomaterials offer unique properties that enable precise control over drug release, enhanced targeting of specific tissues or cells, and reduced side effects. This article explores the contemporary progress in functional nanomaterials for drug delivery platforms, highlighting their potential applications, challenges, and future directions.

Introduction to functional nanomaterials

Functional nanomaterials are engineered structures with dimensions on the nanometer scale (1-100 nm) and tailored properties for specific applications. These materials can be synthesized from various substances, including polymers, lipids, metals, and ceramics, each offering distinct advantages in drug delivery. The functionalization of nanomaterials allows for the incorporation of therapeutic agents, targeting ligands, imaging agents, and stimuli-responsive components, enabling precise control over drug delivery and therapeutic outcomes.

Tailoring nanomaterials for drug delivery

One of the key advantages of functional nanomaterials is their ability to be tailored to meet specific requirements for drug delivery. By adjusting parameters such as size, shape, surface chemistry, and payload encapsulation, researchers can optimize nanomaterials to achieve desired drug release kinetics, biodistribution, and pharmacokinetics. For example, polymeric nanoparticles can be modified to prolong circulation time in the bloodstream, while lipid nanoparticles can be engineered to enhance cellular uptake and intracellular drug release.

Enhanced targeting and accumulation

Functional nanomaterials offer enhanced targeting capabilities, enabling the selective delivery of drugs to diseased tissues or cells while minimizing off-target effects. Targeting ligands, such as antibodies, peptides, or small molecules, can be conjugated to the surface of nanoparticles to recognize specific receptors or biomarkers overexpressed in diseased tissues. This targeted approach improves drug accumulation at the site of action, leading to increased therapeutic efficacy and reduced systemic toxicity.

Controlled drug release

Precise control over drug release is a hallmark feature of functional nanomaterials for drug delivery. Stimuli-responsive nanocarriers can release therapeutic agents in response to external stimuli such as pH, temperature, light, or enzymatic activity present in the diseased microenvironment. This on-demand drug release strategy enhances therapeutic efficacy, minimizes premature drug leakage, and reduces the risk of adverse effects associated with systemic drug exposure.

Applications in disease treatment

Functional nanomaterials have shown promise in the treatment of various diseases, including cancer, infectious diseases, neurological disorders, and inflammatory conditions. In cancer therapy, nanomedicines can selectively target tumor cells, overcome multidrug resistance, and deliver synergistic drug combinations for improved treatment outcomes. In infectious diseases, nanocarriers can enhance the bioavailability of antimicrobial agents and facilitate intracellular drug delivery to infected cells. Moreover, in neurological disorders, nanomaterials can bypass the blood-brain barrier and deliver therapeutics to the central nervous system, offering new avenues for neuroprotection and neuroregeneration.

CONCLUSION

Functional nanomaterials hold immense promise as versatile platforms for drug delivery, offering enhanced targeting, controlled release, and improved therapeutic outcomes. With continued research, innovation, and interdisciplinary collaboration, functional nanomaterials are poised to revolutionize the field of drug delivery and pave the way for personalized and precision medicine approaches. By addressing existing challenges and exploring new avenues for application, functional nanomaterials have the potential to transform the treatment landscape for a wide range of diseases, ultimately improving patient care and quality of life.
