Abstract

Cost-effective, portable, and rapid smartphone sensors will play a critical role in bringing chemical detection technologies from central laboratories to simple laboratories, such as those of schools in less-developed area. In this work, we study whether eggs in Yinchuan have a higher concentration of ovalbumin than that in ordinary eggs. We summarise previous research on sensors built inside smartphones, as well as some developments in the current literature, and develop a simple experimental procedure that utilises the light sensor of a smartphone to analyse light intensity and thereby determine the ovalbumin content of egg white cheaply and quickly. Most of the materials required for conducting this experiment can be easily found in simple school laboratories, and it allows solution concentrations to be quickly assessed by high school students in the data collection and analysis phase. Indeed, the data collected using smartphone light sensors were similar to those obtained using a spectrometer. It was concluded that egg white ovalbumin concentration in eggs collected from Yinchuan is higher than that in ordinary eggs.

Highlights

Due to continuous developments in science and technology, smartphones have become rich in features, while their cost has gradually reduced; at present, smartphones that are fully equipped with a variety of sensors are available for under 150 U.S dollars
Compared to costly and bulky digital information system (DIS), which costs around 1,500 U.S dollars for a kit, smartphones are a cheaper and more portable alternative that is more suitable for laypeople, researchers conducting field survey, and students conducting scientific experiments in resource-limited areas
Selenium has been proposed to have a role in protein synthesis. e local soil of Yinchuan is rich in selenium. us, it is ideal to check whether the eggs in Yinchuan have a higher concentration of ovalbumin than that in ordinary eggs

Summary

Introduction

Due to continuous developments in science and technology, smartphones have become rich in features, while their cost has gradually reduced; at present, smartphones that are fully equipped with a variety of sensors are available for under 150 U.S dollars. Is report describes an experiment to determine the egg white ovalbumin concentration in eggs collected from Yinchuan, using the built-in light sensor of a smartphone. Ovalbumin concentration is measured using an ultraviolet and visible spectrophotometer; certain citizen science squares and high schools cannot afford expensive visible spectrophotometers for communities and groups of students To overcome this difficulty, a new saltingout-based method for ovalbumin extraction from egg white and determination of ovalbumin concentration was developed in this study. It is emphasised that the ovalbumin concentration of the egg white can be measured using the built-in light sensor found in a cheap smartphone. Is experiment focuses on utilising the built-in light sensors of smartphones to measure the ovalbumin concentration of egg white and involves the following steps:. Materials and Methods e equipment required for this experiment included one 50 mL volumetric flask, two quartz cuvettes
