The carbohydrates present on the cells surface can act as a receptor for many pathogens to facilitate cell-cell adhesion through which humans can be infected, for example, mannose binds pathogenic bacteria E. coli and sialic acid binds influenza virus. Therefore, cell surface can be mimicked by preparing SAMs of carbohydrates to study and understand different types of binding and inhibition studies in vitro. SAMs of carbohydrates are also used for detecting disease biomarkers and carrying drugs.…

2.4 IL-DLLME procedures For IL-DLLME under optimum conditions, 10 mL of the sample solution containing Cd2+ or Ni2+ and PAN (10−5mol L−1) was adjusted to pH in a glass test tube with a conical bottom test tube. Using a microsyringe, the mixture of the extraction solvent ([Hmim][PF6]) and disperser solvent (acetonitrile) was rapidly injected into the previously mentioned aqueous sample. A cloudy solution (water, acetonitrile and [Hmim][PF6] ) was formed in the test tube. The ions reacted with…
