The utility of biomaterials has expanded to areas of tissue, blood, biological fluids etc. Replacement and repair of skeletal parts is one of the major areas of application of biomaterials. This review article focuses its attention on the use of biopolymers based nanocarriers for delivering immunomodulatory agents. The role of biopolymers is to modulate, suppress and stimulate innate or adaptive immune system. Based on the data available, nanoparticles can direct the immune system by improving cellular uptake efficiency and modulating the immune system. Nutrients and trace elements such as Se, Mg, etc., can boost the immune system. Plant derived immunomodulators are known and nanosystems find applications as a carrier system for immunomodulatory drugs. This review details the various nanocarriers and the factors affecting the immunomodulation of nanoparticles. https://www.nanomedicine-rj.com/article_247460_0ba0502ea303fb4debe2f55e47206ec1.pdfTehran University of Medical SciencesNanomedicine Research Journal2476-34896320210901Antibacterial effects of impregnated scaffolds with solid lipid nanoparticles gels containing three essential oils against standard and clinical strains of Pseudomonas aeruginosa and Staphylococcus aureus21822724746110.22034/nmrj.2021.03.002ENAlireza ValizadehDepartment of Medical Nanotechnology, School of Advanced Technologies in Medicine, Tehran University of Medical Sciences, Tehran, IranAbbas AbdollahiDepartment of Microbiology, School of Medicine, Fasa University of Medical Sciences, Fasa, Iran.Negar RanjbarNoncommunicable Disease Center, Fasa University of Medical Sciences, Fasa, IraHamid Reza KelidariPharmaceutical Sciences Research Center, Mazandaran University of Medical Sciences, Sari, IranHassan SereshtiDepartment of Analytical Chemistry, School of Chemistry, Colleague of Sciences, University of Tehran, Tehran, IranMahmoud OsanlooDepartment of medical nanotechnology, schools of advanced technologies in medicine, Fasa university of medical sciences (FUMS), Fasa, Iran.Journal Article20211020Wound healing is a complicated process that is affected by physiological and environmental conditions. An antibacterial agent and a physical supporter as wound dressing improve wound healing time and process. In this study, solid lipid nanoparticles (SLNs) containing Mentha longifolia, Mentha pulegium, and Zataria multiflora essential oils with a particle size of 103±5, 195±4, and 130±7 nm were first prepared, and they were then transformed to gels. After that, scaffolds of electrospun polycaprolactone-alginate nanofibers (165±37 nm) were prepared. Chemical properties, surface hydrophilicity, and size and morphology of scaffolds were investigated using ATR-FTIR, contact angel, and SEM analyses. The gels were physically impregnated at two different amounts on the scaffolds, and antibacterial effects at 2, 6, and 24 h of incubation times were determined using the ATCC100 method. Impregnated scaffold with SLNs gel containing Z. multiflora essential oil showed higher antibacterial activity against all standard and clinical bacterial strains at incubation times. The growth of Staphylococcus aureus decreased by more than 90% in all incubation times. Besides, more than 60% reduction in the growth of Pseudomonas aeruginosa was observed after 24 h incubation time. As high potency and green constituents of the prepared prototype, it could be considered for clinical trials.https://www.nanomedicine-rj.com/article_247461_185965fd577c34d5c3a7d4effda75f65.pdfTehran University of Medical SciencesNanomedicine Research Journal2476-34896320210901Fourier Transform Infrared Spectroscopy as diagnostic tools for bladder cancer treatment: Doxorubicin and Cisplatin and Reduced Graphene Oxide as nanocarrier22823624746310.22034/nmrj.2021.03.003ENWagner J.FávaroInstitute of Biology, University of Campinas0000-0001-5830-8938Renata A.,VillelaCidade Universitaria, Barão Geraldo UNICAMPHelder J.CeragioliEEC, University of CampinasNelson DuranCidade Universitaria, Bar&atilde;o Geraldo UNCAMP0000-0001-8372-5143Journal Article20210305Aim: The use of Fourier Transform Infrared Spectroscopy (FTIR) as diagnostic tools for bladder cancer associate to histopathology analysis.<br />Material and Methods: FTIR imagens of normal and bladder cancer tissues in rats o Brucker model V 70 spectrophotometer equipped with the MCT detector (Mercury Cadmium Telluride), under attenuated total reflectance (ATR).

A polysaccharide and its silver nanoparticle from the Ziziphus spina-Christi plant have not yet been tested for their ability to fight liver cancer. Methods:Using a microwave-assisted extraction method, we extracted polysaccharide from the leaves and synthesized silver nanoparticles. The polysaccharide amount, availability, and nanoparticle properties were investigated using the phenol-sulfuric acid process, FT-IR, SEM, TEM, and XRD. The anticancer activity of crude polysaccharide and its polysaccharide coated AgNPs were investigated using the HepG2 cancer cells,MTT assay, cell morphology, cell cycle, reactive oxygen species (ROS), and apoptosis. Results:The existence of predominantly spherical shapes and various sizes (24.10, 29.77, 31.63, 47.7, 56, and 71.5) nm polysaccharide coated AgNPs was confirmed by SEM and TEM analysis. Using the Debye-Scherrer formula, XRD analysis revealed six peaks corresponding to the crystalline size (D value) of AgNPs. Polysaccharide-coated AgNPs outperformed raw polysaccharide against HepG2 cancer cells. Polysaccharide had an IC50 of 1.5 mg/ml in the MTT assay, while polysaccharide coated AgNPs had an IC50 of 0.705 mg/ml. Raw polysaccharide arrested cells in the S process, while polysaccharide coated AgNPs arrested cells in the G1 phase, according to flow cytometry study. Furthermore, raw polysaccharide late apoptosis was lower than late apoptosis of nanoparticles induced by reactive oxygen species. Conclusion:The findings indicated that polysaccharide coated AgNPs derived from Ziziphus spina-Christi polysaccharide could be developed as an anticancer agent against liver cancer and that further research for potential applications is warrantedhttps://www.nanomedicine-rj.com/article_247464_aee3cb66f8daacacf461167267f14956.pdfTehran University of Medical SciencesNanomedicine Research Journal2476-34896320210901Antimicrobial activity and drug delivery ability of Functionalized Multi-Walled Carbon Nanotubes Nanofluid on staphylococcus aureus24825624746510.22034/nmrj.2021.03.005ENMojgan Sheikhpour12 Farvardin streetHengameh JannatiDepartment of Biology, Science and Research Branch, Islamic Azad University, Tehran, Iran.Seyed Davar SiadatDepartment of Mycobacteriology and Pulmonary Research, Pasteur Institute of Iran, Tehran, Iran.Parvaneh SafarianDepartment of Biology, Science and Research Branch, Islamic Azad University, Tehran, Iran.Journal Article20210425Background: Staphylococcus aureus (S. aureus) is a gram-positive bacterium, which has been considered an important nosocomial pathogen worldwide, owing to its increasing antibiotic resistance.
