Infectious diseases seriously threaten human health, and various infectious diseases may cause millions of severe cases and even death every year. Vaccination has been one of the most effective public health interventions in history, preventing millions of deaths worldwide. However, the success of vaccines relies not only on the antigens they carry but also on additional components known as vaccine excipients.

Surfactants are substances used to reduce the surface tension of target solutions. It has fixed hydrophilic and lipophilic groups and can be aligned on the solution surface. The molecular structure of surfactants is amphoteric, with a hydrophilic end group and a hydrophobic end group. The hydrophilic group is polar and usually consists of carboxylic acid, sulfonic acid, sulfuric acid, amino or amine groups, and its salt. In contrast, the hydrophobic group is often referred to as a non-po

Food nutrition enhancer, also called food nutritional fortifier, refers to natural or synthetic nutrients added to food in order to increase its nutritional content. It can not only supplements people's daily nutritional intake, but also has a positive effect on disease prevention and control. The

The three main components of tissue engineering applications are scaffold, cell and growth-stimulating signals. Collagen has been widely used in the clinical field due to its abundance in nature, biocompatibility, low antigenicity and biodegradability. In addition, the high tensile strength and fibril-forming ability of collagen enable it to be made into various forms such as tissue grafts, hydrogels, sponges, fibers, films, hollow spheres, and so on. The wide choice of manufacturing techniqu

Electrospinning can produce continuous fibers on the micro - and nano-scale. The high flexibility and low cost of the material make electrospinning very attractive. In addition, the high specific surface area, porosity, and similarity to ECM ensure that the electrostatic pad promotes cell adhesion, skin regeneration, nutrient and oxygen transport, moisture retention, exudate removal, and hemostasis. Therefore, electrospinning nanofibers are particularly suitable for wound dressings and other
