: Currently, despite many active compounds have been introduced to the treatment, cancer remains one of the most vital causes of mortality and reduced quality of life. Conventional cancer treatments may have undesirable consequences due to the continuously differentiating, dynamic and heterogeneous nature of cancer. Recent advances in the field of cancer treatment have promoted the development of several novel nanoformulations. Among them, the lipid coated nanosized drug delivery systems have gained an increasing attention by the researchers in this field owing to the attractive properties such as high stability and biocompatibility, prolonged circulation time, high drug loading capacity and superior in vivo efficacy. They possess the advantages of both the liposomes and polymeric nanoparticles which makes them a chosen one in the field of drug delivery and targeting. Core-shell type lipid-coated nanoparticle systems, which provide the most prominent advantages of both liposomes such as biocompatibility and polymeric/inorganic nanoparticles such as mechanic properties, offer a new approach to cancer treatment. This review discusses design and production procedures used to prepare lipid-coated nanoparticle drug delivery systems, their advantages and multifunctional role in cancer therapy and diagnosis, as well as the applications they have been used in.

Background: Among the numerous bio-responsive polymeric drug delivery systems developed recently, redox-triggered release of molecular payloads have gained great deal of attention, especially in the field of anticancer drug delivery. In most cases, these systems rely on disulfide bonds located either in the matrix crosslinks, or in auxiliary chains to achieve stimuli-responsive drug release. These bonds keep their stability in extracellular environments, yet, rapidly break by thiol–disulfide exchange reactions in the cytosol, due to the presence of greater levels of glutathione. Polysaccharides are macromolecules with low cost, natural abundance, biocompatibility, biodegradability, appropriate physical and chemical properties, and presence of numerous functional groups which facilitate chemical or physical cross-linking. Methods: With regards to the remarkable advantages of polysaccharides, in the current study, various polysaccharide-based redox-responsive drug delivery systems are reviewed. In most cases the in vitro/in vivo effects of the developed system were also evaluated. Results: Considering the hypoxic and reducing nature of the tumor microenvironment, with several folds higher glutathione levels than the systemic tissues, redox-sensitive polymeric systems could be implemented for tumorspecific drug delivery and the results of the previous researches in this field indicated satisfactory achievements. Conclusion: According to the reviewed papers, the efficiency of diverse redox-responsive polysaccharide-based nanoparticles with therapeutic payloads in cancer chemotherapy could be concluded. Nevertheless, more comprehensive studies are required to understand the exact intracellular and systemic fate of these nano-carriers, as well as their clinical efficacy for cancer treatment.

Nanotechnology has enabled the development of novel therapeutic strategies such as targeted nanodrug delivery systems, control and stimulus-responsive release mechanisms, and the production of theranostic agents. As a prerequisite for the use of nanoparticles as drug delivery systems, the amount of loaded drug must be precisely quantified, a task for which two approaches are currently used. However, both approaches suffer from the inefficiencies of drug extraction and of the solid-liquid separation process, as well as from dilution errors. This work describes a new, reliable, and simple method for direct drug quantification in polymeric nanoparticles using attenuated total reflection Fourier transform infrared spectroscopy, which can be adapted for a wide variety of drug delivery systems. Silk fibroin nanoparticles and naringenin were used as model polymeric nanoparticle carrier and drug, respectively. The specificity, linearity, detection limit, precision, and accuracy of the spectroscopic approach were determined in order to validate the method. A good linear relation was observed within 0.00 to 7.89% of naringenin relative mass with an R2 of 0.973. The accuracy was determined by the spike and recovery method. The results showed an average 104% recovery. The limit of detection and limit of quantification of the drug loading content were determined to be 0.3 and 1.0%, respectively. The method’s robustness is demonstrated by the notable similarities between the calibrations carried out using two different equipment setups at two different institutions.

Dendrimers are emerging class of nanoparticles used in targeted drug delivery systems. These are radially symmetric molecules with well-defined, homogeneous, and monodisperse structures. Due to the nano size, they can easily cross the biological membrane and increase bioavailability. The surface functionalization facilitates targeting of the particular site of action, assists the high drug loading and improves the therapeutic efficiency of the drug. These properties make dendrimers advantageous over conventional drug delivery systems. This article explains the features of dendrimers along with their method of synthesis, such as divergent growth method, convergent growth method, double exponential and mixed method, hyper-core and branched method. Dendrimers are effectively used in anticancer delivery and can be targeted at the site of tumor either by active or passive targeting. There are three mechanisms by which drugs interact with dendrimers, and they are physical encapsulation, electrostatic interaction, chemical conjugation of drug molecules. Drug releases from dendrimer either by in vivo cleavage of the covalent bond between drugdendrimer complexes or by physical changes or stimulus like pH, temperature, etc.

Current Status

Although progress is observed in cancer treatment, this disease continues to be the second leading cause of death worldwide. The current understanding of cancer indicates that treating cancer should not be limited to killing cancer cells alone, but that the target is the complex tumor microenvironment (TME). The application of nanoparticle-based drug delivery systems (DDS) can not only target cancer cells and TME, but also simultaneously resolve the severe side effects of various cancer treatment approaches, leading to more effective, precise, and less invasive therapy. Nanoparticles based on proteins derived from silkworms’ cocoons (like silk fibroin and sericins) and silk proteins from spiders (spidroins) are intensively explored not only in the oncology field. This natural-derived material offer biocompatibility, biodegradability, and simplicity of preparation methods. The protein-based material can be tailored for size, stability, drug loading/release kinetics, and functionalized with targeting ligands. This review summarizes the current status of drug delivery systems’ development based on proteins derived from silk fibroin, sericins, and spidroins, which application is focused on systemic cancer treatment. The nanoparticles that deliver chemotherapeutics, nucleic acid-based therapeutics, natural-derived agents, therapeutic proteins or peptides, inorganic compounds, as well as photosensitive molecules, are introduced.

: Nanoparticles have been widely used in cancer therapy because of its nanoscale, high surface ratio, multifuntions and so on. With specific construction of nanoparticles, such as choosing magnetic nanomaterials or citric acid coated nanoparticle, scientists can kill tumor cells effectively and accurately，importantly， reducing the side effect of conventional chemotherapy. Currently, they have been continually applied in cancer therapeutics research. Scientists not only designed nanoparticles loading with therapeutic drugs, but also equipped with targeted molecules. These works make nanoparticles become a multifuntional nanocarrier. In the construction of multifunctional nanocarriers, nanoparticles play the important work of drug delivery. Normally, enabling drugs delivery to tumor tissues is a difficult task. During the period of internal circulation, it is hard to keep the nanocarriers stability. As well as not attach to normal cells or serum. With the application of stimulus-responsive nanomaterials, scientists develop many nanocarriers with controllable drug release. These controllable drug delivery systems can quickly respond to microenvironmental changes (PH, enzyme, etc.) or external stimuli (photo, heat, magnetic or electric fields). Thus, it is to overcome the side effects by controllable drug delivery systems in vivo. In this article, we summarize the various kinds of stimulus-responsive nanocarriers for cancer therapy and discuss its possibilities and challenges in future application.
