Essays on Biological Activities

Introduction:

Nanobiotechnology serves as an imperative technique in the development of clean, nontoxic, and eco-friendly procedures for the synthesis and congregation of metal NPs having the intrinsic ability to reduce metals by specific metabolic pathways. Silver nanoparticles are particularly interesting nanoscale systems due to the ease with which they can be synthesised and modified chemically. Synthesis of silver nanoparticles has been widely researched due to their interesting size and shape-dependent properties [26]. These novel properties can be tailored by controlling their size, shape, composition, structure and crystallinity. Due to their size features and advantages over available anti-microbial properties, chemical imaging ...

Hansch Analysis

Hansch analysis is used widely in the field of medicinal chemistry. It is the analysis that investigates the quantitative relationship and correlation between the compound’s biological activities with their physicochemical substituents. The global parameters considered in this method include the electronic, steric, hydrophobic, and other effects that use multiple correlation methodology (IUPAC). Application of the Hansch analysis includes the Quantitative Structure-Activity Relationship (QSAR). This application develops correlations between activity of the ligands and their properties. As a rule of the thumb, the Hansch model “gives information about the number of parameters to be selected for regression analysis in ...

1. An alien on Mars can be able to detect life on the planet earth. The earth’s atmosphere contains plenty of oxygen and methane that exists naturally there. These gases can be detected by spectroscopy whereby the light reflected off the earth is split into the different colors that it is composed of. Then the elements present on the planet earth are established according to the colors that the elements emit and absorb. These elements present enable scientists to know the existence of life on earth. This unique method of detecting life on earth is according to the ...
