Zinc oxide (ZnO) is an inorganic compound and it usually appears as a white powder. The powder is widely used as an additive into numerous materials. Inorganic nanoparticles are made by combining organic materials with inorganic materials which forms hybrids and has unique properties. The biological properties of zinc oxide nanoparticles like absorption coefficient, refractive index, concentration, conductivity, pH-values and temperatures were investigated. The diffusion techniques facilitate the measurement of the biological properties of liquids. The results show that absorption coefficient decreases with increasing the thickness of the zinc oxide pellet. The resistivity of the ZnO decreases with increasing the temperature was observed. The concentration of the sample increases conductivity also decreases. Zinc oxide refractive index changes with wavelength. The pH depends on temperature and biological effects were observed at lower concentration and which are playing a vital role in the metabolism of human beings and plant systems. The pH-profiles were measured after 24 h. One-way ANOVA showed significant differences of all tested materials. Variant refractive index can generate resonant cavity that can enhance phase shift of output light and fabricate a variety of optoelectronic device. Materials of high thermal conductivity are widely used in heat sink applications and materials of low thermal conductivity are used as thermal insulation. The biological properties like absorption coefficient, refractive index, concentration, conductivity, pHvalues and temperature were used in many advanced biological, medical and engineering applications such as heat exchangers.
