The development of novel delivery systems for targeted drug delivery represents a significant advancement in medical science and pharmaceutical technology. These innovative systems, including nanoparticles, liposomes, and hydrogels, offer potential solutions for improving the efficacy, safety, and precision of therapeutic interventions [1,2]. Nanoparticles, typically ranging in size from 1 to 100 nanometers, have emerged as a powerful tool in targeted drug delivery. Their small size and large surface area allow for the efficient encapsulation and delivery of therapeutic agents. Furthermore, surface changes can be included in nanoparticles to enhance their stability, biocompatibility, and targeting abilities [3].
One of the primary advantages of nanoparticles is their ability to pass through biological barriers and reach specific tissues or cells. This is particularly important for targeting tumors, as nanoparticles can exploit the Enhanced Permeability and Retention (EPR) effect observed in cancerous tissues [4]. The EPR effect allows nanoparticles to accumulate preferentially in tumor tissues due to their leaky vasculature and poor circulation of lymph. Nanoparticles can be designed from various materials, including lipids, polymers, metals, and inorganic compounds [5]. For instance, polymeric nanoparticles made from biodegradable materials such as PLGA (Poly Lactic-co-Glycolic Acid) have gained significant attention due to their controlled release properties and biocompatibility. Moreover, surface modifications with ligands, antibodies, or peptides can enhance the specificity of nanoparticles for targeted delivery to particular cell types or receptors, thus improving therapeutic outcomes [6].
Liposomes are spherical vesicles composed of one or more phospholipid bilayers, resembling the structure of cell membranes. Their unique structure allows for the encapsulation of both hydrophilic and hydrophobic drugs, providing an adaptable structure for drug delivery. Liposomes have been extensively studied and utilized in various clinical applications due to their biocompatibility, low toxicity, and ability to protect encapsulated drugs from degradation [7]. One of the critical features of liposomes is their capacity for surface modification. By attaching targeting ligands such as antibodies, peptides, or small molecules to the liposome surface, researchers can achieve selective binding and uptake by specific cells or tissues. This targeted approach minimizes off-target effects and enhances the therapeutic index of the encapsulated drug [8].
Hydrogels are three-dimensional, hydrophilic polymer networks capable of retaining large amounts of water or biological fluids. Due to their high water content and biocompatibility, hydrogels are excellent for controlled drug delivery systems. One of the significant advantages of hydrogels is their ability to provide sustained and localized drug delivery [9]. Drugs can be added to the hydrogel structure to achieve controlled release over longer times, which lowers the need for frequent dosage and increases patient compliance. Additionally, hydrogels can be injected or implanted at specific sites, ensuring localized delivery to target tissues or organs. In the field of regenerative medicine, hydrogels have shown great potential for delivering growth factors, cytokines, and other bioactive molecules to promote tissue repair and regeneration. For instance, injectable hydrogels loaded with stem cells or growth factors have been analyzed for applications such as wound healing, cartilage repair, and cardiac tissue regeneration [10]. The ability of hydrogels to create a favorable microenvironment for cell growth and differentiation further enhances their therapeutic potential.
One of the primary challenges of liposome, and hydrogel-based drug delivery systems is the need for precise control over drug release kinetics. The possibility for toxicity and immunogenicity presents another difficulty [11]. Even though many of the components utilized in these delivery methods are biocompatible, there is always a chance of harmful consequences or unfavorable immunological reactions, especially when controlling these materials repeatedly [12]. Therefore, extensive preclinical and clinical studies are necessary to evaluate the safety and efficacy of these systems. Moreover, scalability and manufacturing processes need to be optimized to ensure the reproducibility and costeffectiveness of these advanced delivery systems. The transition from laboratory-scale production to large-scale manufacturing requires overcoming technical and regulatory problems, which can be time-consuming and expensive.
