Technical information "Transdermal absorption evaluation using three-dimensional cultured human skin with TOF-SIMS and LC/MS/MS" and two other items have been released.

Distribution evaluation and quantitative analysis of the same sample are possible.

In recent years, the development of alternative methods to animal testing has progressed in the efficacy and safety testing of pharmaceuticals and cosmetics, with particular attention being paid to testing methods using three-dimensional cultured human skin. In this case study, a permeation test of indomethacin was conducted using a Franz cell, and TOF-SIMS and LC/MS/MS measurements were performed on the same skin sample. LC/MS/MS was used to quantify skin concentration and skin permeation, while TOF-SIMS was used to evaluate the component distribution within the skin. Measurement methods: TOF-SIMS, LC/MS, cryo-processing, cutting Product fields: Biotechnology, pharmaceuticals, cosmetics Analysis objectives: Composition distribution evaluation, safety testing For more details, please download the materials or contact us.

Visualization of nanoscale roughness on the skin surface using AFM.

In recent years, the development of alternative methods to animal testing for the efficacy and safety testing of pharmaceuticals and cosmetics has been progressing, with particular attention being paid to testing methods using three-dimensional cultured skin. In this case study, a percutaneous absorption test of a cosmetic (lotion) was conducted using three-dimensional cultured human skin, which was measured using AFM (Atomic Force Microscopy). This allows for a visual evaluation of the microstructure of the skin surface, and it is also possible to quantitatively assess the roughness of any specific area. By measuring under atmospheric conditions, it is possible to observe the samples while minimizing alterations that would occur under vacuum conditions.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
