Trace level determination of various types of analyte using selective chemosensor: a general survey

Trace level determination of analyte is an extremely important phenomenon and highly relevant area of environmental science, biology, medicine and pharmacology. In this review we have described different type of chemosensor that have been used so far for trace level determination of different types of analyte. Applications of chemo sensor in the arsenic determination have been discussed here. Determination of amino acid by fluorescence spectroscopy has been depicted. Detection of poisonous organic analytes by chemosensor have been made. Some chemosensors have been found to be effective to the determination of selective cations. Various techniques used for determination of analyte by using chemo sensor as well as probable sensing mechanism have been explained here.

Sensing organic analytes by metal–organic frameworks: a new way of considering the topic

In this review, our goal is comparison of advantageous and disadvantageous of MOFs about signal-transduction in different instrumental methods for detection of different categories of organic analytes.

Strong enhancement of gold nanoparticle chemiresistor response to low-partitioning organic analytes induced by pre-exposure to high partitioning organics

A method to enhance the gold nanoparticle sensor response to weak analytes is demonstrated by pre-exposing the sensor to an analyte which elicits a strong response. This weak analyte effectively reduces the strong analyte interaction with the sensor.

Chemically modified electrodes with MOFs for the determination of inorganic and organic analytes via voltammetric techniques: a critical review

Current status on MOF-modified electrodes for voltammetric analyses of inorganic/organic species is critically discussed. We provide future research directions and specific criteria that MOFs should satisfy prior to their use as electrode modifiers.
