The method of making thin film humidity sensors uses thermal vapor deposition or drop casting techniques to fabricate nickel phthalocyanine-fullerene-based (NiPc-C60) quick response humidity sensors with negligible hysteresis. Prior to the deposition of aluminum electrodes, a glass substrate is cleaned by using acetone in an ultrasonic bath for 10 minutes. After cleaning, the substrate is washed with de-ionized water and then dried. A gap is created between two electrodes by masking the glass substrate with copper wire. This assembly is plasma-cleaned for 5 minutes in a thermal evaporator. Subsequently aluminum (Al) thin films are deposited on the assembly. Next, a mixture of equal parts NiPc-C60 is deposited onto the gap between the Al electrodes by thermal vapor deposition or by drop casting. A method of forming NiPc-graphene oxide (NiPc-GO) humidity sensors without using instrumentation drop casts an NiPc-GO suspension onto aluminum foil electrodes taped to a substrate.

The invention discloses a spectrophotometric method for quantifying total lipid content and its application. According to the depolymerization mechanism of lipids to phthalocyanine aggregates, tetra-sec-octyloxynickel phthalocyanine is used as a colorimetric material and petroleum ether is used as a solvent. Quantification of total lipid content. There are three steps: (1) Make a standard curve. Prepare a specific concentration of phthalocyanine solution, use pressed peanut oil as standard lipid, and oil-free sample solution as reference, analyze at 675nm, and fit the coordinate points between absorbance and peanut oil concentration to obtain a linear equation. (2) Lipid extraction. Weigh the sample to be analyzed, extract, evaporate the solvent and weigh to recover the lipid. (3) Total lipid quantification. Take 2.5mL of phthalocyanine solution, mix it with 0.5mL of the recovered lipid sample, and use the lipid-free sample solution as a reference, analyze at the characteristic wavelength, remove the absorption of the same volume of lipid sample, and substitute into the linear equation to calculate the lipid concentration and the corresponding lipid amount and total fat content. Compared with the traditional extraction / weighing method, this method is more accurate and can avoid the influence of residual solvent in the recovered sample.
