Introduction: Nanoemulsion is an important tool in the nano-technological arena designed for clinical and therapeutic application. Currently among different nanocarriers, nanoemulsions are extensively envisaged as carters efficient in targeting oleophillic pharmacologically active constituents at the site of action. Beauties of nanoemulsion include optical clarity, biocompatibility, non-immunogenic, biodegradable, drug encapsulati Read More

Introduction: At the end of 2014, almost 36.9 million people were living with HIV which has put the HIV infection in the list of major public health issues. Although almost thirty drugs are available for the treatment of HIV infection, challenges associated with delivery of these drugs still remain a major concern. These challenges can be divided into three categories 1) poor drug concentration at potential viral reservoirs, 2) poor Read More

Introduction: Cervical cancer is one of the most common gyneocological malignancies among women. E6 and E7 oncoproteins of Human Papillomavirus (HPV) are the main reasons of cervical cancer, other factors include increased level of estrogen, smoking, unprotected sex, and multiparity etc. Nanotechnology appears to be a remarkable alternative to cervix cancer treatment provided that nanoparticles exhibit Read More

Introduction: This study was aimed at determining the optimum condition for desorption of cadmium loaded carbon nanotubes (cCNTs) for re-adsorption of the same metal ion. Materials and Methods: Two independent parameters (contact time and HCl concentrations) were subjected to statistical optimization by face centered central composite design (FCCCD). Result: Maximum desorption cCNT was achieved under the o Read More

Introduction: Fast dissolving films have received great attention in pharmaceutical industry because of their unique properties and advantages. The drug loaded films undergo quick disintegration in the salivary fluids of the oral cavity and release the drug. The purpose of this study is to fabricate tuberculosis (TB) drugs such as Isoniazid and Rifampicin loaded polymer films. Materials and Methods: Three polymers such as poly(vinyl Read More

Introduction: The effluence of Bi3+ doping on the microstructure and property of the undoped and Bi3+-doped Cu2Se films deposited by chemical bath deposition were studied. Methods: The films showed average UV-visible transmittances of ~73.29-84.10 % that increased with increasing Bi3+ content. The optical bandgaps calculated from optical spectra increased with increasing Bi3+ content. Strong bandgap emission at ~62 Read More

Background: The conventional gel formulations employed for the treatment of seborrheic dermatitis, are commonly responsible for dandruff and considered to be less efficacious owing to their low viscosity, low retentivity and faster hydration properties when applied to hair and scalp. Objectives: The antidandruff gel formulations are considered to be highly efficacious over the conventional available formulations due to Read More

Introduction: A systematic theoretical investigation of exciton sizes, their nature and natural transition orbital analysis has been presented for a number of graphene nanoflakes of varying shapes, sizes and isomeric forms. Interestingly, a variation in exciton sizes has been correlated to the size of the structure. The electron delocalization upon absorption has been presented using the natural transition orbital analysis and it i Read More

Background: The Single-wall Carbon Nanotubes (SWCNTs) represent one of the most active classes of nanostructures, and they have been widely used as active materials for important applications.

Objective: Using these investigations, it is possible to obtain much more data to apply SWCNTs in medical sci Read More

Introduction: Green synthesis of nanoparticles has been gaining a lot of attraction owing to its property to synthesize stable nanoparticles by a simple and convenient method. Materials and Methods: The present study demonstrates the use of Dicoma tomentosa bark extract in the synthesis of silver nanoparticles (DT-AgNPs). The formation of DT-AgNPs was indicated by change of color from light brown yellow to dark brown a Read More

Background: Foot-and-Mouth disease (FMD), a contagious, acute infectious disease of domestic and wild ruminants, can devastate livestock and create an economic calamity for their owners. The finding of antiviral compounds to combat FMD virus (FMDV) is thus of great importance. Silver nanoparticles (AgNPs) have attracted great interests as a potentially useful tool for controlling various microorganisms. Objective: In this Read More

Small size 3±0.5nm alumina (Al2O3) nanoparticles have been prepared using control precipitation method in aqueous solution. Aluminum nitrate and ammonium carbonate were added to heated distilled water. Aluminum hydroxide was formed and calcined at 550 oC to produce boehmite (-Al2O3) nanoparticles. The novelty of this work is the surface modification of the formed -Al2O3 nanoparticles, characterized by their low Read More

Carbon-cobalt nanostructures 1 and 2 were prepared by pyrolysis of the cisdichlorobis( 1,10-phenanthroline-N,N')-cobalt(II) complex 3 in the absence or presence of anthracene respectively. DFT calculation was used to estimate ligand dissociation energy of cobalt complex, the energy cost for the formation of cobalt particles which catalyze the formation of carbon nanostructures. FE-SEM analysis indicates that 1 and 2 Read More

Introduction: The preparation and exploration of catalytic activity of nanoparticles in organic transformations have become a genuine need of clean and sustainable chemistry if they are non-toxic, readily available, and recyclable.
