Both P25TiO2NPs (with or without vitamin B2) were not found beyond the epidermis in 99% of the analyzed TEM images (Fig. 8). This is coherent with previous findings showing that nanoparticles greater than 50 nm can not penetrate the skin, even in vivo models with movement, stretching, and friction [54]. However, in one of the zones, a few nanoparticles were observed inside a hair follicle. This could be due to the follicle exposure after the localized rupture of this physical barrier when rats were shaved in order to clean the area for cream topical administration. This finding suggests that nanoparticle-based sunscreen should not be applied on recently shaved or harmed skin, in order to avoid nanoparticle skin penetration.

At its core, a walking foot machine is designed with a unique feeding mechanism that allows the presser foot to walk along with the fabric as it moves through the machine. This mechanism is particularly beneficial when working with multiple layers of thick materials such as leather, canvas, or upholstery fabrics, which can be challenging to sew with standard sewing machines. The walking foot evenly feeds the layers of fabric through the machine, preventing slippage and ensuring that all layers move at the same pace. This results in a more consistent stitch quality and minimizes the risk of puckering or distortion.
