“…However, nanoparticles still have limitations such as instability in circulatory system and toxicity. Polymers due to their amazing properties are used in a wide range of applications, such as batteries, coatings, adhesives, solar cells, drug carriers, and Prosthesis [40][41][42][43][44][45][46]. They can be suitable carriers and prevent premature destruction of the drug and improve their stability and prolong the presence of the drug in the circulatory system.…”

Advances in medicine and pharmacy have saved many lives from death. Researchers and scientists around the world have made great strides with their findings, not only improving public knowledge with their findings but also keeping hope alive in the hearts of some people with incurable diseases. Various sciences accompanied medicine and pharmacy in this development, one of which is polymer engineering. Polymers due to amazing properties can be used as prostheses, drug carriers, gene delivery, etc. Polymers are unique candidates for the release of anticancer drugs. Non-toxicity, and biodegradability are important features of a carrier. This study summarizes cancer statistics and introduces several polymer-carriers.

“…Polysulde polymers as adhesives and sealants are known as highly-resistant materials to solvents and chemicals and have excellent weathering resistance properties. [1][2][3][4] They are commonly synthesized by condensation polymerization of dihalides such as 1,4-dibromo-2-butene, 5 styrene dibromide, 6 and 1,4-bis(chloromethyl)-benzene 7 with sodium polysulphides. Polysulphide polymers with tetrasulphide linkages show a rubber-like behaviour 8 whereas their low thermal stability is their main disadvantage.…”

A novel approach was used to fabricate poly(ethylene tetrasulphide) (PETS)-modified graphene nanosheets.Accordingly, graphene oxide (GO) was modified with (3-chloropropyl)triethoxysilane (CPTES) to yield GO-Cl with the ability of participation in interfacial polymerization of 1,2-dichloromethane (EDC) and disodium tetrasulphide (Na 2 S 4 ) and synthesis of graphene/PETS nanocomposites. Also, to investigate the effect of surface chemistry of the nanosheets on the properties of the nanocomposites, GO-Cl nanosheets were reduced by hydrazine monohydrate to obtain rGO-Cl. The success of modification and reduction of the nanosheets was confirmed by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Then, two series of nanocomposites containing different contents of GO-Cl and rGO-Cl were synthesized. Proton nuclear magnetic resonance ( 1 H NMR) was used to determine the molecular weights of the polymers. Also, dispersion of the nanosheets in the polymeric matrix was studied by XRD and thermal stability and the thermophysical properties of the nanocomposites were investigated by TGA and differential scanning calorimetry (DSC) respectively.Results showed that incorporation of the nanosheets leads to lower molecular weights of the polymeric matrix whereas reduced nanosheets were dispersed more appropriately in the matrix. According to the TGA results, the dispersion of nanosheets and molecular weight of the matrix were prominent factors in the thermal stability of the nanocomposites. Also, all samples showed a glass transition temperature (T g ) less than 0 C, a cold crystallization temperature (T cc ), and a subsequent melting point (T m ) which were affected by the content of nanosheets.

“…Also, polymers have many applications in the medical field for reasons such as biodistribution and biocompatible [42][43][44][45][46][47][48]. They can be good carriers and prevent premature destruction of the drug and improve their stability and prolong the presence of the drug in the circulatory system [49][50][51][52][53]. In addition, polymers can carry multiple drugs at the same time, which can be very useful for treatment [54][55][56][57].…”

Cancer is one of the leading causes of death in the world and is the third leading cause of death in most countries after traffic accidents and cardiovascular mortality [1][2][3][4]. Cancer has become a major public health problem in the world and every day, many people in different parts of the world are going to die cause of cancer [5,6]. Also, cancer and its treatment can weaken the immune system and reduce the ability to fight infections, thus increasing the risk of death from infectious disease [7]. In recent years, with increased greenhouse gases and weather change, and environmental pollution, human health is increasingly at risk and the incidence of cancer has risen in some countries [8][9][10][11][12][13][14][15][16][17][18][19][20]. Breast, colorectal, and stomach cancers are the most common cancers for women, and stomach, prostate, and colorectal cancers are the most common cancers in men [21,22]. Breast cancer is known as the most common malignancy among women and causes many deaths every year [23]. Despite many advances in the early diagnosis and proper treatment of this disease, it is still the leading cause of death among women [24-26]. The disease originates from breast tissue cells. When normal cells in the breast begin to change and grow uncontrollably and they form tumors, at which point cancer begins [27]. The tumor is identified after the biopsy as non-cancerous or malignant. Breast cancer affects women between the ages of 15 and 85. Studies have shown that patients with breast cancer are exposed to a lot of stress that can cause psychological and social disorders in their lives.The most important risk factors for breast cancer are age, sex, family history of cancer, and hormonal factors. Fortunately, cancer treatment has progressed amazingly, surgery, chemotherapy, and radiotherapy can destroy tumors and arrest cancer progression [28,29]. In recent years, the use of nanotechnology to diagnose and treat cancer has made significant progress [30][31][32]. Nanoparticles have the ability to penetrate cancer cells and can increase the concentration of drugs in them [33,34]. Carbon nanomaterials such as nanotubes, expanded graphite, graphene, and graphene oxide are ARTICLE INFO ABSTRACTEvery day we see progress in medicine and the treatment of many diseases. Cancer has been associated with human life for more than two decade and every day, many people in different parts of the world are going to die cause of cancer. Breast cancer is the most common among women. However, with the advancement of medical science, many cases can be treated. There are several sciences involved in this treatment, one of which is polymer engineering. Polymers have many applications in the treatment field for reasons such as biodistribution and biocompatible. Also, polymers are unique candidates for the release of anticancer drugs. This study briefly introduces breast cancer and several polymer-carriers.
