Usage

Uses

Used in Surface Modification:
7-CARBOXY-1-HEPTANETHIOL is used as a self-assembled monolayer (SAM) for surface modification of gold electrodes. This modification is crucial for various applications, such as quartz crystal microbalance (QCMB) measurements.
Used in Biomedical Applications:
In the biomedical industry, 7-CARBOXY-1-HEPTANETHIOL is used as a monolayer that facilitates ferritin absorption on gold electrodes. This application aids in the uptake of excess iron in cells, which can be beneficial for certain medical treatments or diagnostics.
Used in Photothermal Therapy:
7-CARBOXY-1-HEPTANETHIOL is also used in the preparation of nitric oxide-based gold nanoparticles (NO-AuNPs) for macrophage photo-thermal therapy under near-infrared (NIR) irradiation. This application is particularly relevant in the field of cancer treatment, where localized heating can be used to target and destroy cancer cells.
