“…In the reverse microemulsion method, the spherical micelles are formed by adding a surfactant to an organic solvent that is transparent and thermodynamically stable. The preparation of silica nanoparticles occurs in the interface of the micelles [167]. In the chemical vapor deposition method, which is also called the high temperature flame decomposition method, precursors such as silicon tetrachloride are brought into the vapor phase to be prepared for nucleation [168,169].…”

This review provides a summary of recent progress in the development of different nano-platforms for the efficient synergistic effect between photodynamic therapy and chemotherapy. In particular, this review focuses on various methods in which photosensitizers and chemotherapeutic agents are co-delivered to the targeted tumor site. In many cases, the photosensitizers act as drug carriers, but this review, also covers different types of appropriate nanocarriers that aid in the delivery of photosensitizers to the tumor site. These nanocarriers include transition metal, silica and graphene-based materials, liposomes, dendrimers, polymers, metal–organic frameworks, nano emulsions, and biologically derived nanocarriers. Many studies have demonstrated various benefits from using these nanocarriers including enhanced water solubility, stability, longer circulation times, and higher accumulation of therapeutic agents/photosensitizers at tumor sites. This review also describes novel approaches from different research groups that utilize various targeting strategies to increase treatment efficacy through simultaneous photodynamic therapy and chemotherapy.

“…Since the early 1980s, water in oil (w/o) or an inverse microemulsion mechanism has been utilized to prepare metal nanoparticles as well as minerals. The technique of microemulsion has various advantages in a dispersion medium over all other polymerization techniques and offers the possibility of preparing a wide range of colloidal particles with diverse characteristics . This approach is not successful at the industrial level owing to large oil (solvent) quantity usage, surfactants, and poor nanoparticle yield .…”

Over the past few years, engineered inorganic nanoparticles have been studied researched, and applied extensively in the biomedical field since resultant platforms increase the usage of the nanoparticles for particular theranostic applications. The innovation of such nanosystems has the potential to develop a theranostic mode that integrates both diagnosis and treatment of diseases in a particular system via combinatorial approaches of imaging, targeting, and therapy that accomplish the potential of personalized and tailored medicine. The manipulation of magnetic nanoparticles (MNPs) as theranostic agents have attained growing consideration in material science owing to their exclusive capability in magnetic targeting, magnetic resonance imaging, chemotherapy, hyperthermia, bioseparation, gene therapy, enzyme immobilization, and controlled release of the drug. To intensify the diagnostic and therapeutic efficacy, MNPs have been ornamented or functionalized with a range of materials to enhance the biocompatibility, stability, and capability to carry therapeutic payloads and to encapsulate imaging agents. Preferentially synthetic and natural polymers have been exploited to coat for ensuring their colloidal stability and good dispersibility in biological fluids. Stimuli-responsive polymers have also been used to functionalize MNPs to establish a therapeutic approach that can significantly enhance therapeutic effectiveness including the real-time monitoring in specific cells and tissues. The present review highlights the progress of MNPs emphasizing functionalization using diverse inorganic and organic and biomaterials. Furthermore, it also provides the soundproof concept on the potential of MNPs and their colloidal counterparts that offer attractive possibilities for theranostic applications. Finally, the main challenges and limitations in the use of MNPs for advanced biomedical applications have also been critically provided.

“…19 Besides, silica coating on IONPs has been promising because of its biocompatibility, and ease of further functionalization with other polymers, and molecules. 20,21 In addition to that, the surface of IONPs have also been modied with some other organic ligands, e.g., catechol and phosphocholine group containing molecules, that have very high affinity to anchor with metal oxide nanoparticles' surface. 22 Dopamine has emerged great interest as capping agent for IONPs due to the stability and strength of the resultant ve-membered metallocycle chelate and the ease at which it can be functionalized through amide bonds with other molecules of interest.…”
