    , Article Iranian Polymer Journal (English Edition) ; Vol. 23, issue. 5 , May , 2014 , p. 387-403 Eskandari, M ; Hosseini, S. H ; Adeli, M ; Pourjavadi, A ; Sharif University of Technology
    The increasing importance of nanotechnology in the field of biomedical applications has encouraged the development of new nanomaterials endowed with multiple functions. Novel nanoscale drug delivery systems with diagnostic, imaging and therapeutic properties hold many promises for the treatment of different types of diseases, including cancer, infection and neurodegenerative syndromes. Carbon nanotubes (CNTs) are both low-dimensional sp2 carbon nanomaterials exhibiting many unique physical and chemical properties that are interesting in a wide range of areas including nanomedicine. Since 2004, CNTs have been extensively explored as drug delivery carriers for the intracellular transport of... 

    Fabrication of PLA/PEG/MWCNT electrospun nanofibrous scaffolds for anticancer drug delivery

    , Article Journal of Applied Polymer Science ; Volume 132, Issue 3 , August , 2015 ; 00218995 (ISSN) Anaraki, N. A ; Rad, L. R ; Irani, M ; Haririan, I ; Sharif University of Technology

    In the present study, polylactic acid (PLA)/polyethylene glycol (PEG)/multiwalled carbon nanotube (MWCNT) electrospun nanofibrous scaffolds were prepared via electrospinning process and their applications for the anticancer drug delivery system were investigated. A response surface methodology based on Box-Behnken design (BBD) was used to evaluate the effect of key parameters of electrospinning process including solution concentration, feeding rate, tip-collector distance (TCD) and applied voltage on the morphology of PLA/PEG/MWCNT nanofibrous scaffolds. In optimum conditions (concentration of 8.15%, feeding rate of 0.2 mL/h, voltage of 18.50 kV and TCD of 13.0 cm), the minimum experimental... 

    Poly(N-isopropylacrylamide)-coated β-cyclodextrin–capped magnetic mesoporous silica nanoparticles exhibiting thermal and pH dual response for triggered anticancer drug delivery

    , Article International Journal of Polymeric Materials and Polymeric Biomaterials ; Volume 66, Issue 7 , 2017 , Pages 336-348 ; 00914037 (ISSN) Pourjavadi, A ; Mazaheri Tehrani, Z ; Sharif University of Technology

    In this research a novel controlled anticancer drug delivery system with dual pH and thermal responses was designed based on magnetic mesoporous silica nanoparticles that were anchored by β-cyclodextrin and coated by poly(N-isopropylacrylamide) (PNIPAM). Results demonstrated that the behavior of doxorubicin (anticancer drug) release depended on pH and temperature conditions. At endosomal pH (pH 5.5) the amount of drug release enhanced because the cap was removed from the pores. Furthermore, PNIPAM shell collapsed above the lower critical solution temperature and the releasing of drug increased. Thus, this nanocarrier would have the potential to be applied in the tumor therapy. © 2017 Taylor... 

    Diatoms with invaluable applications in nanotechnology, biotechnology, and biomedicine: Recent advances

    , Article ACS Biomaterials Science and Engineering ; Volume 7, Issue 7 , 2021 , Pages 3053-3068 ; 23739878 (ISSN) Rabiee, N ; Khatami, M ; Jamalipour Soufi, G ; Fatahi, Y ; Iravani, S ; Varma, R. S ; Sharif University of Technology

    Diatoms are unicellular microalga found in soil and almost every aquatic environment (marine and fresh water). Biogenic silica and diatoms are attractive for biotechnological and industrial applications, especially in the field of biomedicine, industrial/synthetic manufacturing processes, and biomedical/pharmaceutical sciences. Deposition of silica by diatoms allows them to create micro- or nanoscale structures which may be utilized in nanomedicine and especially in drug/gene delivery. Diatoms with their unique architectures, good thermal stability, suitable surface area, simple chemical functionalization/modification procedures, ease of genetic manipulations, optical/photonic... 

    A possible anticancer drug delivery system based on carbon nanotube-dendrimer hybrid nanomaterials

    , Article Journal of Materials Chemistry ; Volume 21, Issue 39 , 2011 , Pages 15456-15463 ; 09599428 (ISSN) Mehdipoor, E ; Adeli, M ; Bavadi, M ; Sasanpour, P ; Rashidian, B ; Sharif University of Technology
    Iron oxide nanoparticles, γ-Fe2O3NP, were deposited onto the surface of multi-walled carbon nanotubes and CNT/γ-Fe2O3NP hybrid nanomaterials were obtained. Then linear-dendritic ABA type block copolymers consisting of polyethylene glycol as B block and poly(citric acid) as A block, PCA-PEG-PCA, were synthesized and cisplatin (cis-diamminedichloroplatinum (CDDP) - a platinum-based chemotherapy drug) was conjugated with their carboxyl functional groups and CDDP/PCA-PEG-PCA anticancer prodrugs were prepared. Noncovalent interactions between CDDP/PCA-PEG-PCA anticancer prodrugs and CNT/γ-Fe2O3NP hybrid nanomaterials led to CDDP/PCA-PEG-PCA/CNT/γ-Fe2O3NP drug delivery systems. There are several... 

    Smart nanostructures for cargo delivery: uncaging and activating by light

    , Article Journal of the American Chemical Society ; Volume 139, Issue 13 , 2017 , Pages 4584-4610 ; 00027863 (ISSN) Karimi, M ; Sahandi Zangabad, P ; Baghaee Ravari, S ; Ghazadeh, M ; Mirshekari, H ; Hamblin, M. R ; Sharif University of Technology
    Nanotechnology has begun to play a remarkable role in various fields of science and technology. In biomedical applications, nanoparticles have opened new horizons, especially for biosensing, targeted delivery of therapeutics, and so forth. Among drug delivery systems (DDSs), smart nanocarriers that respond to specific stimuli in their environment represent a growing field. Nanoplatforms that can be activated by an external application of light can be used for a wide variety of photoactivated therapies, especially light-triggered DDSs, relying on photoisomerization, photo-cross-linking/un-cross-linking, photoreduction, and so forth. In addition, light activation has potential in photodynamic...
