The present invention provides novel diazonaphthoquinonesulfonic acid bisphenol derivatives. More particularly, the present invention relates to photo restive coating comprising alkali-soluble resin, a photoactive compound and a surfactant. The photoresist film prepared has less then one micron. The photoactive compound is soluble or swellable in aqueous alkaline solutions and is diazonaphthoquinonesulfonic bisphenol esters of the general formula (A), wherein DNQ represents a 2-Diazo-1-naphthoquinone-4-sulfonyl, 2-Diazo-1-naphthoquinone-5-sulfonyl, 1-Diazo-2-naphthoquinone-4-sulfonyl groups and R1 R1 represents an alkyl, aryl and substituted aryl groups. The invention also provides a process for coating and imaging the light-sensitive composition.

The present invention provides a novel sensor for the estimation of total cholesterol in human blood serum using molecular imprint of cholesterol. Human blood serum contains 150-250 mg/dl cholesterol. The present invention provides a sensor device and a process for the fabrication of ISFET (Ion Selective Field Effect Transister) coated with molecular imprint of cholesterol on the SiO+SiNdielectric gate of the said electrode. The molecular imprint of cholesterol (MIPC) anchored in to a silica matrix sensing material is identified as a sensing material which has specific selectivity towards the cholesterol in presence of other organic constituents in human blood serum.

The present invention relates to the development of a biosensor to determine potassium in human blood serum using dibenzo-18-crown-6 (DB18C6) as ionophore. Human blood serum contains potassium in ppm levels i.e 137 to 200 mg/litre and sodium co exists with a 30 times higher concentration. Such a high concentration tends to interfere the selectivity towards potassium, but DB18C6 proves to have an excellent selectivity towards potassium and is highly sensitive to the lowest concentration of potassium levels present in the human blood serum. So the present invention reports the fabrication and characterization of ISFET (Ion Selective Field Effect transistor) coated with a monolayer of crown ether, dissolved in chloroform, on the gate of electrode.
