Introduction

Enviromental pollution is one of the greatest global issues to this day and it keeps increasing at an alarming level which poses a great danger to human health. The greatest threats are in fact, industrial wastes and pollutants which are constantly released into the enviroment, including the pesticides that consist of organo-phosphorous compounds or either their derivatives [1]. Those pesticided are often used to increase the food production, even though the high amounts of it can have lethal consequences when it comes to human health or food safety. Since the proper remoting of agricultural areas have been problem for decades, because the usual methods like Chromatography Mass Spectroscopy or Liquid/Gas Chromatography are costly, non-portable and require specialized laboratories, scientist have come up with the idea of using cost-effective portable biosensors which could effectively detect the methyl parathion (one of the organo-phosphorous compounds) on spot [2].

Green fluorescent protein

The green fluorescent protein (GFP) is a protein that sucessfully exhibits green fluorescence when exposed to light in the blue to ultraviolet range and GFP usually refers to the protein first isolated from the jellyfish Aequorea victoria. Also, GFP-like coral proteins exhibit a broad spectral diversity ranging from blue to red FPS, so both the stability and expression of it could be optimized by amino acids substitutions possessing different kinds of biophysical properties, therefore such modifications could ensure better rate of maturation and stability of mentioned FPs. Such modificated and more stable monomeric FPs could be used as biosensors [3].
