Physical factors that will enhance effectiveness

Physical) factors that will enhance effectiveness... 

The term elicitor refers to chemicals from various sources, biotic or abiotic, as well as physical factors, that can trigger a response in living organisms resulting in a high accumulation of secondary metabolites. Therefore, elicitors are usefiil tools for improving the production of plant valuable compounds ([36] and references therein). The effectiveness of elicitation as a tool to enhance the production of secondary metabolites depends on a complex interaction between the elicitor and the plant cell. There is evidence that the same elicitor can stimulate secondary metabolism in different cell cultures and that certain plant cultures are responsive to diverse elicitors. Treatment of a particular plant cell culture with different elicitors will result in the accumulation of a particular class of compounds, since these are specific of each plant culture. Although the class of metabolite depends on the plant species, the kinetics of induction or accumulation levels can vary with different elicitors. 

Leddy and Vanderborgh showed that deposition of Nafion into the cylindrical pores of Nucleopore polycarbonate membranes enhanced mass transport of electroactive cations to the surface of the electrode by an order of magnitude (75). It appears that morphological changes on the 0.01-0.1 micron scale can lead to chemical effects on the atomic/molecular/ionic level for this and other systems. It will take some time to understand the factors controlling such features of a microstructure. Interfacial chemical and physical interactions control such phenomena, and are some of the most difficult to examine experimentally.
