Testing samples were made mixing 100 uL of TiO2NPs suspensions (0.2 mg/mL and 0.02 mg/mL) and vitamins@P25TiO2NPs (0.2 mg/mL and 0.02 mg/mL) with 100 μL ATCC 29,213 methicillin-sensitive Staphylococcus aureus (MSSA) (107 in PBS, pH 7). Controls were made replacing nanoparticles with the same volume of PBS. The concentrations of nanoparticle suspensions were chosen based on the FDA approved maximal and the minimal amount usually found in sunscreens, which are 20% and 2% (this is equivalent to 0.2 mg/mL and 0.02 mg/mL for nanoparticles suspensions). The cream concentration, on the other hand, was an intermediate value of 10%.

China is one of the largest producers and consumers of titanium dioxide powder in the world. There are numerous titanium dioxide powder factories in China, mainly located in Sichuan, Shandong, Guangdong, and other regions. These factories adopt advanced technology and equipment to produce high-quality titanium dioxide powder. They not only supply domestic market but also export to Europe, America, Asia, and other regions. In addition to China, there are also many titanium dioxide powder factories in other countries such as the United States, Japan, and Germany In addition to China, there are also many titanium dioxide powder factories in other countries such as the United States, Japan, and Germany In addition to China, there are also many titanium dioxide powder factories in other countries such as the United States, Japan, and Germany In addition to China, there are also many titanium dioxide powder factories in other countries such as the United States, Japan, and Germanytitanium dioxide powder factories. These factories compete with each other in terms of product quality, price, and service to meet the needs of different customers.
