In recent years, significant advancements have been made in drug delivery systems using microneedles. Researchers have developed a rocket microneedle drug delivery system that uses a self-propulsion mechanism for deep penetration into the skin and tumor microenvironment. This article discusses the use of rocket microneedles made of mesoporous silica nanoparticles and other materials for the treatment of melanoma, a type of skin cancer.

​Quantum dots (QDs) refer to semiconductor nanoparticles with a size smaller than the Bohr radius of the exciton and exhibiting quantum confinement effects. Due to the quantum confinement effect, the fluorescence emission of quantum dots is related to their diameter and chemical composition. By compounding with semiconductor surfaces, their optical and photochemical properties can be enhanced. Traditional quantum dots are mostly composed of heavy metal elements. Although their excellent performance has been widely used in fields such as biological imaging, electrochemistry, and energy conversion, heavy metal elements can cause environmental pollution and affect the health of organisms.

​Introducing Nano Nickel Powder - the revolutionary product that's changing the game when it comes to industrial materials. If you're looking for high quality, reliable and cost-effective nickel powder, you've come to the right place.

Alpha and Gamma alumina are two of the most widely used types of alumina in various industrial applications. Though both types are derived from the same raw material, they differ in terms of properties, structures, and behaviour, making them suitable for distinct applications. In this blog post, we will explore the differences between alpha and gamma alumina and how these differences impact their functionality.

Silicon carbide powder has become a popular material in various industries due to its unique properties like high hardness, high wear resistance, and excellent thermal conductivity. There are two types of silicon carbide powder, Alpha SiC and Beta SiC. In this article, we will explore the differences between the two types of silicon carbide powder and their applications.

A dispersant is a chemical substance used to disperse nanoparticles in solution or solid. Its basic principle is to interact with the surface of nanoparticles, change surface characteristics, reduce the attraction between particles, and achieve the dispersion of nanoparticles.
