DDSs from Electrospun Beads-on-a-String Nano Products

The development of nanotechnology has revolutionized multiple industries and continues to offer a broad spectrum of potential applications. From its initial theoretical and experimental research stages, nanotechnology has progressed towards practical application, addressing a myriad of real-world problems. Nanomaterials are extensively utilized across various sectors (including electronic storage, water and air filtration, the food industry, healthcare, the pharmaceutical industry, etc.) [ 1–4 ]. The indispensability of nanomaterials has spurred researchers to continuously challenge and innovate in nanotechnology. The aim of nanotechnology applications is to develop new materials with enhanced performance [ 5–6 ]. For instance, polymer nanoparticles have numerous applications in electronics, photonics, medicine, biotechnology, pollution control, and environmental technology, and serve as conductive materials, sensors, and more. Nanofibers can act as carriers for cell and tissue regeneration, serve as structural scaffolds in wound dressings, and function as integral components in drug delivery systems (DDSs) [ 7–8 ]. Liposomes, which are vesicles composed of phospholipid bilayer membranes, are used as micro-nano carriers and show great potential in gene delivery and cancer treatment. Dendritic polymers, which mimic the characteristics of micelles, liposomes, and certain biomolecules, are employed as drug carriers and immunogens [ 9–10 ]. Nanomaterials for different applications can be designed and manufactured through appropriate methods. Numerous techniques exist for preparing these nanomaterials, including electrospinning, electrospraying, the sol-gel process, phase separation, template synthesis, etc.
