“…Usually, magnetic responsive behavior can be imparted by incorporating magnetic NPs (MNPs) as a dispersion in a cross-linked polymeric matrix rendering responsive behavior against magnetic stimuli 142 . With the change of magnetic state, the mechanical, thermal, and acoustic behavior also get affected simultaneously as the magnetic part behaves as a composite along with the hydrogel matrix 143 .…”

“…These are networks of hydrophilic polymers that contain a high amount of water or physiological fluids. The hydrogels exhibit a high biocompatibility and important therapeutical properties [40,[68][69][70][71][72]. When nanogels are used, interactions between materials and living cells are possible, and different types of drugs can be delivered.…”

Recently, magnetic nanoparticles (MNPs) have more and more often been used in experimental studies on cancer treatments, which have become one of the biggest challenges in medical research. The main goal of this research is to treat and to cure advanced or metastatic cancer with minimal side effects through nanotechnology. Drug delivery approaches take into account the fact that MNPs can be bonded to chemotherapeutical drugs, nucleic acids, synthetized antibodies or radionuclide substances. MNPs can be guided, and different treatment therapies can be applied, under the influence of an external magnetic field. This paper reviews the main MNPs’ synthesis methods, functionalization with different materials and highlight the applications in cancer therapy. In this review, we describe cancer cell monitorization based on different types of magnetic nanoparticles, chemotherapy, immunotherapy, magnetic hyperthermia, gene therapy and ferroptosis. Examples of applied treatments on murine models or humans are analyzed, and glioblastoma cancer therapy is detailed in the review. MNPs have an important contribution to diagnostics, investigation, and therapy in the so called theranostics domain. The main conclusion of this paper is that MNPs are very useful in different cancer therapies, with limited side effects, and they can increase the life expectancy of patients with cancer drug resistance.

Hydrogels are hydrophilic polymer networks that absorb any kind of liquid including biological fluids. Natural polymers and their derivatives along with synthetic polymers are used to form the hydrogels. Networks that constitute the hydrogels are created by the crosslinking of either synthesized polymers starting from monomers or already developed polymers. Crosslinking can be developed either physically if secondary intermolecular forces are involved or chemically in which a covalent bond between polymeric chains is created. Gelatins are natural driven protein polymers. One of the main biopolymers used for producing hydrogels is gelatin. Gelatin has a very wide application other than hydrogels. In this review, hydrogels and their property and synthesis mechanism, as well as their application in biomedical along with gelatin chemistry and application, are reviewed. Due to its nonimmunogenicity, nontoxicity, low cost, and high availability gelatin-based hydrogels could find applications in drug delivery carrier, bioink, transdermal therapy, wound healing, and tissue repair. The beneficiation of gelatin can result in their sustainable conversion into high-value biomaterials on the proviso of the existence or development of cost-effective, sustainable technologies for converting this biopolymer into useful bioproducts.
