Case 1: Assembly of tin oxide nanosheets for hydrophobic/hydrophilic coating and cancer detection
In an aqueous solution, Alfa Chemistry crystallized tin oxide nanosheets on fluorine-doped tin oxide transparent conductive oxide substrates. The chemical ratio of the nanosheets is Sn:O:F = 1:1.85:0.076. They have a contact angle of 140° and are hydrophobic surfaces. Light irradiation converts them to hydrophilic surfaces with contact angles of less than 1°.

Surface coatings of polymers, metals, biomaterials, paper, and other materials will be treated with this easy water treatment. Hepatocellular carcinoma patients' serum contains monoclonal antibodies that react with human fetoprotein. Under excitation light, the nanosheets produced photoluminescence and photocurrent. As electrodes for prostate cancer sensors, tin oxide nanosheets customized with prostate-specific antigens tagged with dyes can be employed.
Case 2: Silica-aluminate epoxy-based sol-gel coating
Alfa Chemistry has created a thin hybrid coating for corrosion and wear protection of tin substrates using a sol-gel technique. When loaded with zirconia particles, this consists of a silica-aluminate epoxy-based sol-gel coating that acts as a barrier and increases mechanical characteristics. The dense layer of densely loaded zirconia coating on top of the outer layer acts as a barrier to water and ion penetration.
