  • Abstract Many studies show that the metallic glasses exhibit better properties, such as high strength, hardness, corrosion resistance, larger elastic energy storage and electrical or magnetic. Nowadays, it is more easily to fabricate the thin film metallic glasses, which have been used widely in industry, such as optical film, biomaterial or micro-electro-mechanical-system (MEMS).
    There are few applications of metallic glasses for antimicrobial properties. Moreover, the metallic thin films with high reflection, such as silver and aluminum, show the good antimicrobial property, especially silver. The weak point of aluminum is also obvious, such as the higher toxicity and the ion release easily, but aluminum as reflective film is good material.
    In this study, it is thus researching the anti-fungal and anti-bacterial activity of Al-Ni-Y metallic glass thin films, to adjust the different Al content to discuss the relationship between reflective and antibacterial activity. First, to synthesize Al-Ni-Y TFMGs on the optical glass with different compositions of Al, then test the resistance and reflectivity, finally do the antibacterial test.
    E. coli and S. aureus, who were Gram-negative bacteria type and Gram-positive bacteria, were chosen to do the antibacterial test, because they are the common bacteria in life. Aspergillus niger, Penicillium rugulosum and Aureobasidium pullulans were chosen to do the antifungal test, because they are growing on the optical glass and instrument.
