Abstract: Aim: The present study aims at exploring the development of xylometazoline hydrochloride loaded chitosan nanoparticles (XYL-NP) cross linked with calcium chloride for treatment nasal congestion. Materials and Methods: XYL-NP were prepared using different polymer like chitosan, linking agent glacial acetic acid as a solvent enhancer ionotropic gelation method, which was further optimiz...

A two-site spatial coagulation model is considered. Particles of masses m and n at the same site form a new particle of mass m + n at rate mn . Independently, particles jump to the other site at a constant rate. The limit (for increasing particle numbers) of this model is expected to be non-deterministic after the gelation time, namely, one or two giant particles randomly jump between the two s...

Background & Aims: In recent years, the feasibility of hydrophilic nanoparticles has been broadly investigated for use in drug delivery and therapeutic systems. Due to the problems of traditional adjuvants, in this study Agkistrodon halys (Ah) Snake venom was loaded in chitosan nanoparticles (CS NPs) in order to be used as an advanced adjuvant and antigen delivery system in ant...

The aim of this study was designing and preparing the chitosan nanoparticles (CS-NPs) loading with snake (Vipera albicornuta) venom as well as evaluating the influence of different factors on the encapsulation efficiency (EE) and loading capacity (LC) of venom. The morphologies and characteristics of CS-NPs were determined by scanning electron microscopy (SEM), Fourier transform infrared spectr...

Manganese zinc ferrite nanoparticles (MZF NPs) were synthesized by using a direct, efficient and environmental friendly hydrothermal method. To improve the colloidal stability of MZF NPs for biomedical applications, NPs were coated with chitosan by ionic gelation technique using sodium tripolyphosphate (TPP) as crosslinker. The synthesized NPs were characterized by X ray diffraction (XRD) analy...

The objective of this work was to characterize the cinnamon oil nanocapsule that contained alginate-chitosan as coating agents. In this work, cinamonn oil loaded chitosan nanoparticles (CS-alginate NP-cinamonn) are prepared by a two-step process including oil/water emulsion and ionic gelation. In this study, cinamon as a core material was nanoencapsulated with chitosan alginate at a ratio of 1:...
