As a promising systemic drug delivery method, transdermal drug delivery system (TDDS) is easier and more convenient to operate than traditional oral, intravenous and subcutaneous injection methods. It can improve patient compliance while also avoiding First-pass effect and drug side effects. As the largest organ of the human body, the skin is also the body’s first line of defense against foreign microorganisms and chemical substances. Its drug permeability is lower, which is orders of magnitude different compared to the epithelial cells of the gastrointestinal tract and lungs. Therefore, how to pass through the many barriers of human skin is the first problem faced during transdermal drug delivery. In the past 20 years, with the continuous development of nanotechnology, various nanoformulations have been increasingly used in transdermal drug delivery.

What is Zeta Potential? Figure 1. Electrical double layer at the surface of solution-phase nanoparticles. Zeta potential (ZP) is a physical property exhibited by any particle in a suspension, macromolecule or material surface. ZP is an analytical technique used to determine the surface charge of nanoparticles in colloidal solutions. The surface of a charged particle attracts and binds firmly to a thin layer of opposite charge, forming a thin layer of liquid called the Stern layer; as the particle diffuses in the solution, it will be replaced by a thin layer of loosely bound ions. The outer diffusion layer is involved, resulting in an electric double layer (Figure 1). Zp is named after the potential of the electric double layer and is determined by measuring the speed of charged particles moving through the sample solution toward the electrode in the presence of an external electric field. ZP values are typically in the range of +100 to −100 mV. The magnitude of the ZP gives a ... Continue reading →

Hydrogel is a three-dimensional network of hydrophilic polymers that swells in water without dissolving. Because the polymer contains a large number of hydrophilic groups, the hydrogel can absorb and lock a large amount of water. After absorbing water, the hydrogel network can maintain its original shape without being destroyed. Hydrogels are widely used in tissue engineering, drug delivery, biosensing, etc. due to their simple preparation, strong tunability of mechanical properties, good biocompatibility, and elasticity and softness that are very similar to most tissues and extracellular matrices of the human body. The field is developing rapidly. Depending on the source from which the hydrogel is prepared, hydrogels can be divided into natural hydrogels and synthetic hydrogels. Due to society’s demand for sustainable products, hydrogels derived from natural materials, especially those from renewable resources, have attracted attention. Among renewable resources, ...
