This research was conducted to formulate biodegradable itraconazole (ITZ)-loaded d-a-tocopheryl polyethylene glycol 1000 succinate-b-poly(e-caprolactone-ran-glycolide) (TPGS-b-(PCL-ran-PGA); TPP) nanoparticles (NPs) (designed as ITZ-loaded TPP NPs) to improve antifungal efficacy. ITZ-loaded TPP NPs were prepared by a modified double-emulsion method, and their size distribution, morphology, zeta...

the combination of graphene (gr) and nickel oxide nanoparticles (nio nps) yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. in cyclic voltammetry (cv) studies, in the presence of ep, nio/gr composite modified electrode shows a significantly higher current response for ep oxidation. based on differential pulse voltamm...

The incorporation of metal oxide nanoparticles (NPs) in fiber filters is an effective approach to enhance the specific surface area and roughness fiber, hence improving their efficiency for fine dust capture other gas treatment or biological applications. Nevertheless, uneven distribution NPs limits practical In this study, a commercial silane coupling agent (3-methacryloxypropyltrimethoxysilan...

Manganese ferrite (MnFe2O4) magnetic nanoparticles were successfully prepared by a sol-gel self-combustion technique using iron nitrate and manganese nitrate, followed by calcination at 150 °C for 24 h. Calcined sample was systematically characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and vibrational sample magnet...

The impacts of Co nanoparticles (NPs) on the anaerobic digestion (AD) cow dung were investigated using kinetic models (modified Gompertze, logistic, and first-order) experimental measurements. deviation between predicted measured data for biogas yield with modified Gompertze logistic 0.66–2.26% 1.43–4.19%, respectively. addition NPs (1–3 mg/L) improved hydrolysis rate (K) value by 66.66–144% co...

The use of nanomaterials in biomolecular labeling and their corresponding detection has been attracting much attention, recently. There are currently very few studies on palladium nanoparticles (Pd NPs) due to their lack of appropriate surface functionalities for conjugation with DNA. In this paper, we thus firstly present an approach to prepare carboxyl group-modified Pd NPs (with an average s...

In this work, we have prepared three types of aptamer-conjugated Rubpy-doped silica nanoparticles for Human breast carcinoma MCF-7 cells labeling. Probe A is prepared through covalent conjugation between amine-labeled MUC-1 aptamer and carboxyl-modified Rubpy-doped NPs (NPs-aptamer). Probe B is prepared based on the interaction between biotin-labeled MUC-1 aptamer and avidin-conjugated Rubpy-do...

Polymer nanoparticles are vehicles used for delivery of hydrophobic anti-cancer drugs, like doxorubicin, paclitaxel or chemopreventors like quercetin (Q). The present study deals with the synthesis and characterisation of nano formulations (NFs) from Q loaded PLGA (poly lactic-co-glycolic acid) nano particles (NPs) by surface modification. The surface of Q-loaded (NPs) is modified by coating wi...

FePt nanoparticles (NPs) were assembled on aluminum oxide substrates, and their ferromagnetic properties were studied before and after thermal annealing. For the first time, phosph(on)ates were used as an adsorbate to form self-assembled monolayers (SAMs) on alumina to direct the assembly of NPs onto the surface. The Al(2)O(3) substrates were functionalized with aminobutylphosphonic acid (ABP) ...
