Highly stable niosomes are prepared and investigated in Tween80/PEG6000/Span80/H2O system. The mean radius of the niosomes is 0.15-0.2 microm. The contents of PEG6000 and Span80 and the system temperature affect the size and the stability of the niosome. A certain Span80 can remarkably improve the stability. The niosome is provided distinctly with the hydrotrope-solubilization action to the hyd...

9 Photoinduced electron transfer (ET) reactions between coumarin dyes and N, N10 dimethylaniline have been investigated inside niosome, a nonionic innocuous 11 Polyethylene glycol (PEG)-based surfactant assemblies using steady state and time12 resolved fluorescence measurements. The location of coumarin dyes has been 13 reported inside bilayer headgroup region of niosome and it was verified by ...

The present study aimed to evaluate the incorporation of protamine into niosome/DNA vectors to analyze the potential application of this novel ternary formulation to deliver the pCMS-EGFP plasmid into the rat retina. Binary vectors based on niosome/DNA and ternary vectors based on protamine/DNA/niosomes were prepared and physicochemically characterized. In vitro experiments were performed in AR...

BACKGROUND The systemic administration of cytotoxic chemotherapeutic agents for cancer treatment often has toxic side effects, limiting the usage dose. To increase chemotherapeutic efficacy while reducing toxic effects, a rational design for synergy-based drug regimens is essential. This study investigated the augmentation of therapeutic effectiveness with the co-administration of paclitaxel (P...

Abstract Purposes Calcium channel blockers, such as diltiazem (DLZ), are important drugs for wound repair treatment. This current study used an ultrasonic method to increase the cutaneous delivery of (DLZ) niosomes. Methods The impact cholesterol:surfactant ratio on DLZ-loaded niosome formulations was investigated. Differential scanning calorimetry (DSC), powder X-ray diffraction (PXRD), electr...

Studies of biological and artificial membrane systems, such as niosomes, currently rely on the use of fluorescent tags, which can influence the system under investigation. For this reason, the development of label-free, non-invasive detection techniques is of great interest. We demonstrate an open-volume label-free millimeter-wave sensing platform based on a coplanar waveguide, developed for id...

Breast cancer is the fifth most common cause of death among women worldwide. Resistance to cisplatin is a main challenge in its treatment. Our present aim was to prepare nanoniosomated cisplatin and examine its efficacy in vitro using the BT-20 cell line. Niosome nanoparticles containing cisplatin were prepared by reverse-phase evaporation and characterized by dynamic light scattering (DLS), sc...

Niosomes have potential applications in topical drug delivery system. The objective of the study was to formulate and evaluate the niosome of Itraconazole. Surfactant : cholesterol ratio and quantity of ethanol used were studied by applying factorial design. Formulated niosomes were evaluated for vesicle size, entrapment efficiency, drug release, skin permeation, and antimycotic activity. Vesic...

Niosomes (nonionic surfactant-based vesicles) containing rifampicin were prepared using various nonionic surfactants of sorbitan ester class and cholesterol in 50:50 percent mol fraction ratio. The drug-entrapped vesicles were characterized for their shape, size, drug entrapment efficiency and in vitro release rate. On the basis of in vitro characterization, the niosomes showing maximum entrapm...

Abstract Background Melittin, a peptide component of honey bee venom, is an appealing candidate for cancer therapy. In the current study, melittin, melittin-loaded niosome, and empty niosome had been optimized anticancer effect assessed in vitro on 4T1 SKBR3 breast cell lines vivo BALB/C inbred mice. "Thin-layer hydration method" was used preparing niosomes; different niosomal formulations meli...
