1. Introduction to Smart Drug Delivery Systems

Smart drug delivery systems represent a transformational change as to how medical agents are administered, which enables accurate targeting of specific tissues or cells while reducing systemic toxicity [1]. These advanced systems include a series of liposomes, polymieric nanops and vasicular structures such as nanocarers, each of which is designed for controlled release, increased bioavailability, and off-target effect [1].

Rapid progress in nanotechnology has fuel innovative designs that respond to stimuli such as pH, temperature, or specific enzymes, allowing the drug release to closely align with physical needs and thus pursue individual medicine [2]. This privatization enables the treatment of individual genetic and molecular profiles, improving medical results by reducing adverse effects [2].

Especially in cancer therapy, nanotechnology provides opportunities to remove biological barriers and accumulate selected drugs in tumors, represents a significant improvement on traditional chemotherapy approaches [3]. However, the region faces complex manufacturing, challenges related to regulatory barriers, and ensure fertility and safety in the form of these nanotechnology, which leads to clinical use [3].

2. Liposomal and Vesicular Drug Delivery Innovations

The liposomal and vasicular drug delivery systems have greatly upgraded the accuracy and efficacy of medical distribution, increasing pharmacocyannetics and reducing systemic poisoning, offering unique abilities to encounter hydrophilic and hydrophobic drugs [4]. The diverse structural versatility of liposomes allows their surfaces to be modified with ligands or polymers for active targeting, which improves the accumulation of the drug in specific tissues and reduces adverse side effects [5].

Current research emphasizes the integration of novel liposomal compositions and manufacturing techniques to improve stability, drug loading efficiency, and controlled-proved behavior, the position of liposomes in the form of important vehicles in modern therapeutic [6]. These innovations include excitement-ex-ex-vesicles that release drugs under specific conditions, such as temperature or pH changes, enabling on-demand drug delivery on target sites [7].

In addition, the liposomal system has a variety of variations, including multilemeler vesicles, small universal vesicles, and large universal vesicles, each of which are suitable for separate clinical applications [8]. Researchers are also focused on raising the circulation time of lipid compositions and surface and by mononuclear phagocyte system to reduce uttake, thus prolonging systemic availability [9].

Extending beyond traditional liposomes, polymeric nanoparticles provide another vesicular platform, distributing drugs with precise size control and biodegradability, although their toxicity and environmental effects require a thorough evaluation [10]. In addition, programmable lipid nanopards represent a state-of-the-art approach, using modular design and domain-specific architecture to improve accurate targeting and better therapeutic results [11].

3. Polymeric Nanoparticles and Programmable Lipid Systems

Polymeric nanopartan has emerged as a versatile carrier in drug distribution, which improves pharmacocinetics and therapeutic efficacy, due to the ability to increase a wide range of medical agents and release them in a controlled manner. A remarkable approach involves designing nanops up with pH-respondent linkage, such as the chiff base, enabling the release of selective drug in the acidic microelement of the tumor while maintaining stability in normal tissues [12].

Beyond the polymer system, programmable lipid nanoparts represent an important innovation, offering accurate targets through structural modifications and adaptable lipid compositions. These systems take advantage of modular architecture that can respond to physiological triggers or include specific ligands for receptor-medium delivery, can increase tissue specificity and reduce systemic side effects [13].

Recent researches have highlighted dextron-docosorubicin product-based nanops as effective pH-sensitive carriers, providing high drug-loading efficiency and controlled drug release, which are important to reduce poisoning and increase medical results in cancer treatments [13]. Such development underscores nanocheriors the convergence of material science and drug technology in crafting that are biocampatible and functional dynamic, which pave the way for individual drug applications [13].

4. pH-Responsive and PEGylated Nanoparticles for Targeted Therapy

PH-responded and peglated nanoparticles represent a large advancement in crossing biological barriers that limit drug distribution, especially in solid tumors. By exploiting acidic tumors microelement, pH-sensitive systems can trigger the drug release especially at the disease site, which reduces systemic poisoning [14]. Such targeted release not only enhances medical index, but also allows to accumulate high drug concentrations on a pathological site compared to traditional distribution systems [14].

Pegylation, the process of attaching polyethylene glycol chains to nanopartical surfaces, improves systemic circulation by reducing opsonization and uptake by reticuloendothelial system. This stearic stabilization is particularly important to achieve passive targeting through increased permeability and retention (EPR) effects, a strategy that is usually applied to cancer nanomedicine [14].

Recent innovations also highlighted the application of microobots and magnetically guided nanops up as emerging tools for site-specific distribution. These platforms can navigate through the body using external magnetic fields, allowing accurate drug localization while reducing off-target exposure [15]. Their clinical capacity is being actively examined for minimal invasive, targeted medical intervention [15].

Additionally, proniosomes provide a steady, pH-respondent vesicular formulation that is capable of converting to niosomes on hydration. These systems increase the entry efficiency and structural stability of the drug, which make them suitable for various delivery routes, including oral, transdermal and parental administrative [16].

5. Effervescent Systems, Proniosomes, and Herbal-Based Drug Delivery

Their rapid disintegration, better patient compliance, and extended bioavailability [17] are used rapidly in oral drug distribution. These systems use acid-base reactions to produce carbon dioxide, enable quick spread and facilitates better gastrointestinal absorption [18]. They are particularly valuable for distributing drugs that require rapid start or better solubility.

Proniosomes, which create niosomes on hydration, offer better chemical stability and ease of storage than traditional vesicular systems. Their application spreads many administration routes and has been effective in improving the distribution of poorly soluble or unstable drugs [18]. Structural structure and surfactent selection vest size, entry efficiency in the drug and release cannteix are important in tune.

Supplements for these systems, herbal-based formulation-like-Tribulus received from Terrestris-have received traction to reduce their medicinal efficacy and toxicity. These plant-based approaches are particularly relevant in chronic treatments such as urolithiasis, where long-term security is necessary [19]. Including herbal agents in modern distribution systems pulls traditional and contemporary pharmacology, expands therapeutic toolkit for chronic and systemic diseases.

In addition, it is important to understand the interaction between nanopartical surfaces and biological environment. Studies suggest that blood protein can adsorb on the surface of the vesicular carrier such as liposomes, changing their pharmacocyannetics and biodistration, thus affecting efficacy and safety profiles [20].

6. Extracellular Vesicles, Safety, and Translational Perspectives

Extraselular vesicles (EVS), including exosomes and microavasicals, have emerged as promising natural nanocherries for drug distribution due to their bio -transportation, ability to overcome biological barriers, and underlying targeting capabilities. They can encounter various types of medical agents and facilitate cell-to-cell communication, making them ideal for accurate drug [21]. Their ability to modify inflammation, distribute small molecules and maintain stability in biological environment connects their medical utility [21].

Liposomal carriers, a type of synthetic vasicular system, have long served as a foundation for drug distribution technologies. Their structural imitation of the biological membrane allows for efficient encapsulation of both hydrophilic and lipophilic drugs. Liposome has performed better pharmacocynetic profiles and reduces systemic poisoning, which paves the way for clinically approved yogas [22]. Their design affects the growth of flexibility EV-mimic platforms.

Smart nanocarers such as Mesoporus silica nanoparticles are also examined for their tuniable por structures and high surface area, allowing site-specific drug loading and controlled release. In colorectal cancer therapy, these systems increase tumor accumulation and selective cytotoxicity, improving medical results, decreasing systemic risk, [23].

The broader landscape of nano technology applications in cancer treatment highlights the developed role of targeted drug delivery. From diagnostics to therapeutics, Nanoscale systems provide equipment to improve efficacy, reduce toxicity and adapt to treatment protocols based on patient-specific characteristics [24].

For translation in clinical settings, scalability, reproduction and regulatory compliance are important. Recent studies emphasize strategies to reduce the difference between laboratory research and commercial drug products and to reduce the difference between laboratory research and commercial drug products by evaluating long -term security [25].
