Nylon is a human‐made material and has been applied in many industrial fields. This literature review explores the use of nylon in biomedical applications and discusses the properties and three‐dimensional (3D) printability of this material. Nylon is studied due to its versatility as an engineering plastic that can be easily transformed into fibers, films, and molded parts. Due to nylon's biocompatible nature, it has desirable chemical stability and tunable mechanical properties making this material and its derivatives widely used as sutures, catheters, dentures, and so on. However, the interactions between nylon and human body tissues have yet to be fully understood. Nevertheless, nylon is hybridized with different materials and used as skin dressings. In recent years, nylon composites have been actively researched in tissue engineering as an alternative to metallic implants with an appropriate bioactivity potential for bone growth. As nylon is supposed to be in contact with the tissue for a long time, hence researchers are developing antimicrobial strategies for the nylon materials to even promote their potential a step further. The 3D printing of nylon is currently confined to specific applications due to the printing technology's current limitations.

Cancer is one of the top life‐threatening dangers to the human survival, accounting for over 10 million deaths per year. Bioactive glasses have developed dramatically since their discovery 50 years ago, with applications that include therapeutics as well as diagnostics. A new system within the bioactive glass family, mesoporous bioactive glasses (MBGs), has evolved into a multifunctional platform, thanks to MBGs easy‐to‐functionalize nature and tailorable textural properties—surface area, pore size, and pore volume. Although MBGs have yet to meet their potential in tumor treatment and imaging in practice, recently research has shed light on the distinguished MBGs capabilities as promising theranostic systems for cancer imaging and therapy. This review presents research progress in the field of MBG applications in cancer diagnosis and therapy, including synthesis of MBGs, mechanistic overview of MBGs application in tumor diagnosis and drug monitoring, applications of MBGs in cancer therapy ( particularly, targeted delivery and stimuli‐responsive nanoplatforms), and immunological profile of MBG‐based nanodevices in reference to the development of novel cancer therapeutics.

Poly(2-hydroxyethyl methacrylate) (pHEMA) as a biomaterial with excellent biocompatibility and cytocompatibility elicits a minimal immunological response from host tissue making it desirable for different biomedical applications. This article seeks to provide an in-depth overview of the properties and biomedical applications of pHEMA for bone tissue regeneration, wound healing, cancer therapy (stimuli and non-stimuli responsive systems), and ophthalmic applications (contact lenses and ocular drug delivery). As this polymer has been widely applied in ophthalmic applications, a specific consideration has been devoted to this field. Pure pHEMA does not possess antimicrobial properties and the site where the biomedical device is employed may be susceptible to microbial infections. Therefore, antimicrobial strategies such as the use of silver nanoparticles, antibiotics, and antimicrobial agents can be utilized to protect against infections. Therefore, the antimicrobial strategies besides the drug delivery applications of pHEMA were covered. With continuous research and advancement in science and technology, the outlook of pHEMA is promising as it will most certainly be utilized in more biomedical applications in the near future. The aim of this review was to bring together state-of-the-art research on pHEMA and their applications.
