The development of effective drug delivery systems is a crusial task for modern medicine. main problem the occurrence non-specific toxicity leading to undesirable side effects in vivo. This article aims at reviewing resent research on polyamidoamine (PAMAM) dendrimers results show that PAMAM and modified nanoparticles depends both characteristics particles themselves (size, generation surface c...
Due to the poor compatibility caused by large difference in hydrophilicity and interface between polylactic acid (PLA) cellulose acetate (CA), blending of two materials is difficult application limited. To solve this problem, a type polyamide amine (PAMAM) dendrimer was introduced modify PLA/CA blends work. The results showed that PAMAM could improve blends, promote distribution CA crystallizat...
A human 3D inflammatory cartilage-on-a chip model was develop as a drug screening platform to evaluate the therapeutic efficacy of anti-TNF? mAb-CS/PAMAM dendrimer NPs loaded-Tyramine-Gellan Gum Hydrogel.
The objective of this study was to determine the cytotoxicity, antiproliferative activity, and apoptosis induction activity of two modified glycosides – digoxin and proscillaridin A – conjugated to a generation 3 polyamidoamine dendrimer (G3 PAMAM-NH ) in human breast cancer cells. The results suggest that conjugation with the G3 PAMAM-NH dendrimer enhances the cytotoxicity of modified digoxin ...
The performance of several palladium precatalysts, namely, palladium(II) acetate, palladium(0) nanoparticles encapsulated into poly(amidoamine) (PAMAM) dendrimers (Pd DENs), and palladium(II)-PAMAM complexes, in the Stille reaction between trichloro(phenyl)stannane and iodoarenes in water is compared. The reactivity of Pd DENs is similar or inferior to that of palladium(II) acetate, although th...
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...
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...
