“…Formulations based on albumin nanoparticles have several advantages, some of which are due to the use of albumin as a structural unit of nanoparticles and others related to the properties of these nanoparticles, and Mathematical modeling plays an important role in facilitating the design of drug delivery systems by identifying key factors and molecular mechanisms of release [ 224 – 227 ]. Which are mentioned below [ 228 , 229 ].…”

In this article, we will describe the properties of albumin and its biological functions, types of sources that can be used to produce albumin nanoparticles, methods of producing albumin nanoparticles, its therapeutic applications and the importance of albumin nanoparticles in the production of pharmaceutical formulations. In view of the increasing use of Abraxane and its approval for use in the treatment of several types of cancer and during the final stages of clinical trials for other cancers, to evaluate it and compare its effectiveness with conventional non formulations of chemotherapy Paclitaxel is paid. In this article, we will examine the role and importance of animal proteins in Nano medicine and the various benefits of these biomolecules for the preparation of drug delivery carriers and the characteristics of plant protein Nano carriers and protein Nano cages and their potentials in diagnosis and treatment. Finally, the advantages and disadvantages of protein nanoparticles are mentioned, as well as the methods of production of albumin nanoparticles, its therapeutic applications and the importance of albumin nanoparticles in the production of pharmaceutical formulations.

“…In fact, this happens to be the range up to which the greatest reduction of permeability is observed. At higher contents the benefits are outweighed due to nanoparticle agglomeration (Picard E. et al, 2015), entrapped air (Salimi M. et al, 2017) and highly mobile polymer free-volume (Wilson R. et al, 2012). These unwanted effects frequently occur simultaneously to one another due to impeded nanocomposite processing at high nanoparticle contents.…”

Car tires, sealing caulk and high-voltage cable insulators are prime examples of commercially available and widely used composites of polymers containing nanostructured particles. In fact, myriads of applications can be realized but the usefulness of such nanocomposites depends heavily on composition, morphology, concentration and dispersion homogeneity of the nanoparticle filler in the polymer matrix. Optimizing these characteristics while ensuring economically feasible fabrication, determines the extent to which new products integrate nanocomposites. This review discusses challenges and manufacturing options of polymer nanocomposites and, in particular, which and how much nanoparticle fillers improve electrical/thermal conductivity, dielectric permittivity, gas permeability, magnetization and mechanical stability by critically reviewing and classifying over 280 peer-reviewed articles. Lastly, the economic, environmental and health implications associated with these materials are highlighted.

“…On the other hand, in most industries, taking into account environmental laws, the need for separation processes is more than ever before [27] . In fact, as the separating processes and the related equipment are so large that in most industries, a large part of the cost of a product is related to the costs of separating and purifying the product [28] . For this reason, finding a simpler separation method at a lower cost can be considered.…”

Poly (vinylidene fluoride) (PVDF) and poly-sulfone (PSF) polymer solutions were made at a concentration of 18% by weight of the polymer as a non-soluble additive of polymer solution in 1-methyl-2-pyrrolidone (NMP) solvent. PVDF and PSF hollow fiber membranes were fabricated via the wet phase-inversion process. Fabricated membranes were characterized in terms of gas permeability, wetting resistance, water contact angle and overall porosity. In order to study the structure of the membranes made, the scanning electron microscopy images of the model (TM3000, HITACHI, Japan) were used. The morphology study indicates that the PSF membrane shows an open cross-section structure with smaller pore sizes. However, the PVDF membrane illustrates a thick sponge-like structure. The fabricated PVDF membrane shows higher wetting resistance, surface porosity, water contact angle, and N2 permeability. The performance of the produced membranes was examined for the Absorption of carbon dioxide in a gas-liquid contactor membrane through the solution of mono-ethanolamine (MEA). The results show that CO2 absorption flux of the PVDF hollow fiber membrane is higher than PSF hollow fiber membrane. The maximum CO2 absorption flux of 8.10 × 10-3 (mole/m2 s) at the liquid phase flow rate of 300 ml/min for PVDF hollow fiber membrane was achieved and also the maximum CO2 absorption flux of 6.50 × 10-3 (mole/m2 s) at the liquid phase flow rate of 300 ml/min for PSF hollow fiber membrane was obtained. It can be concluded that a porous hydrophobic hollow fiber membrane with high surface porosity and high gas permeability can be a productive alternative for CO2 absorption through gas-liquid membrane contactors.
