Electrospinning is considered a promising technology for encapsulating and loading various drugs into nanofibers. Metoprolol tartrate (MPT), hydrophilic therapy, was used as model drug. Metoprolol tartrate was loaded into poly(ɛ-caprolactone) (PCL) via blend and emulsion electospinning. The preparation processes, morphology, chemical structure thermal properties were evaluated. FESEM showed that emulsion electospinning produce larger fiber diameters(301.775nm) when compared to fibers produced by blend electrospinning(112.463, 249.34)nm, the PCL/ span 80 and MPT-PCL by emulsion method which have high fiber diameter than pure PCL and MPT-PCL by blend method and the Tm of pure PCL nanofibers and all drug loaded scaffolds are around 60°C from DSC test, water contact angle to pure PCL electrospun mats hydrophobic character (126.2°), while PCL/span 80, and PCL-drug nanofiber mats showed hydrophilic character. Our study demonstrated the possibility of using electrospinning with a promising good potential toward sustained and controlled drug delivery system.

Delivery of therapeutic compounds to the diseased area in the body with minimized adverse effects is the underlying objective behind development of advanced drug delivery systems. Providing disease-specific release patterns is the ultimate goal of any drug delivery system. Electrospinning has been widely used for nanofiber fabrication. Having high aspect ratio and similarity to the extracellular matrix in the body make electrospun nanofibers a great candidate to be used as drug delivery implants. In this study, we report electrospinning to be a tunable technique capable of providing engineered, disease-specific drug release patterns. Using “one factor at a time” and “central composite design” techniques, we respectively demonstrate flow rate and applied voltage to be the two most significant parameters (with [Formula: see text]-values of 512.48 and 42.31) affecting the final fiber diameter, and capillary-to-collector distance as the least important one, by evaluating their influence, individually and combined, on the morphology of electrospun Poly (Lactide-co-Glycolide acid) nanofibers. Using the same two techniques, we also show that hydrophobicity of the polymeric fibrous scaffold, measured by water contact angle (WCA) with the [Formula: see text]-value of 376.44, is the main factor to consider when designing an electrospun fibrous drug delivery system for a specific disease, while fiber diameter can further modulate the release pattern of the drug from hydrophobic polymeric nanofibers. We finally support our hypothesis by comparing our findings with analysis of data derived from the literature. Taken together, our findings suggest electrospinning to be a tunable technique capable of providing various release patterns for any small molecular weight drug on the basis of the requirements of the diseases to be treated.

Poly (lactic acid) (PLA) is well known for their biodegradability and bioresorbable properties and these properties made them suitable in drug delivery system as drug carriers. PLA is relatively hydrophobic and lack of cell-recognition group to interact with biologically active molecules which reduce the surface compatibility of microspheres. In this project, alkaline hydrolysis was used to induce hydrophilic functional group on the microspheres surface. Alkaline solution at 0.01M and 0.1M was used to modify microspheres surfaces. The engineered surfaces were evaluated using Scanning Electron Microscopy and Water Contact Angle. 0.1M alkaline solution hydrolyzed microspheres at higher extends as compared to 0.01M, where partial microspheres disintegrated and porous structure was revealed. The water contact angle of PLA films shows decreased from 65 ̊ to range 42 47 ̊ after alkaline hydrolysis.

This work has a focus on the self-emulsifying drug delivery system (SEDDS), which can be used in pharmaceutical field for increasing bioavailability of poorly water-soluble drugs. The model drug resveratrol was used because of its poor water-solubility and is of interest because of its wide range of pharmacological effects. It is beneficial to understand the mechanism of SEDDS formation in the human body, therefore, the determination of nanoscale structure was carried out. For this purpose, small angle X-ray scattering (SAXS), photon correlation spectroscopy (PCS), and transmission electron microscopy (TEM) techniques were applied. We have found that the size and size distribution of particles were in nanometers. The inner structure of SEDDS was ordered with the lamellar distances (d-spacing) of < 20 nm. It seems that the prepared SEDDS in water form large oil drops (200-400 nm) in water as well as small micelles with the droplet size of 10-20 nm.
