Among the six Critical Nanoscale Design Parameters (CNDPs) proposed by Prof. Donald A. Tomalia, this review illustrates the influence of the sixth one, which concerns the elemental composition, on the properties of dendrimers. After a large introduction that summarizes different types of dendrimers that have been compared with PolyAMidoAMine (PAMAM) dendrimers, this review will focus on the pro...
دندریمر های pamam، نانو حامل هایی با خصوصیات منحصر به فرد مانند حلالیت آبی بالا، زیست سازگاری و رهایی موثر پیوند دارو- پلیمر در سلول های اسیدی بعد از وارد شدن به سلول های تومور هستند در حالی که این پیوند ها در گردش خون پایدار باقی می مانند. دندریمر تجاری pamam به عنوان یک عامل انتقال موثر در محیط های طبیعی و مصنوعی دارای بازدهی انتقال بالا و سمیت کم به طور همزمان است. با در نظر گرفتن امتیازات د...
chronic hepatitis c might lead to several immunological dysfunctions. studies have shown a positive association between hepatitis c virus (hcv) infection and psoriasis. these results suggest that the infection may be one of the triggering factors for the development or exacerbation of psoriasis. here, we present a case of chronic hcv infection with psoriasis who developed exacerbation of skin l...
A photosensitizing nanosystem based on PEGylated PLGA nanoparticles doped with luminescent molybdenum-iodide nanoclusters displays advantageous features for photodynamic therapy of ovarian cancer.
به دلیل حلالیت بسیار زیاد نیترات در آب، روشهای متداول تصفیه قادر به حذف آن نیستند. این پژوهش با هدف تعیین کارایی نانوکامپوزیت عاملدار شده PAMAM-Go بهمنظور حذف نیترات از محیطهای آبی در مقیاس آزمایشگاهی و بهصورت پایلوت و برای اولین بار در ایران و جهان انجام شد. در این پژوهش سنتز گرافن اکساید بهروش اصلاح شده هومر صورت...
Background: Nanoscale poly (amidoamine) dendrimers have been investigated for their biological demands, but their antibacterial activity has not been widely discovered. Thus, the sixth generation of poly (amidoamine) dendrimer (PAMAM-G6) was synthesized and its antibacterial activities were evaluated on Gram-negative bacteria; P. aeruginosa, E. coli, A. baumannii, S. typhimur...
In recent years, chitosan and its different derivatives have been extensively used in surface modification and functional finishing of textiles. In this study, wool yarns used in handmade carpet were treated with different concentrations of chitosan-poly (amidoamine) dendrimer hybrid (Ch-PAMAM) and characterized by scanning electron microscope (SEM), and their dyeing properties were investi...
Objective:At the present study, relationship between phagocytosis of PLGA particles and combined effects of particle size and surface PEGylation was investigated. Materials and Methods:Microspheres and nanospheres (3500 nm and 700 nm) were prepared from three types of PLGA polymers (non-PEGylated and PEGylation percents of 9% and 15%). These particles were prepared by solvent evaporation metho...
Genuine, nondegraded PAMAM dendrimers self-assemble with siRNA into nanoscale particles that are efficient for siRNA delivery and induce potent endogenous gene silencing.
Accidental exposure to uranium is a matter of concern, as U(VI) is nephrotoxic in both human and animal models, and its toxicity is associated to chemical toxicity instead of radioactivity. We synthesized different PAMAM G4 and G5 derivatives in order to prove their interaction with uranium and their effect on the viability of red blood cells in vitro. Furthermore, we prove the effectiveness of...
