Abstract
Objectives: Design, fabrication and characterization of different shapes of PDMS based fluidic channels without clean room process to give the consumer an opportunity for detection of few common adulterants in milk. Methods/Statistical Analysis: The detail fabrication process of PDMS based microchannel and experimental analysis carried out for determination of adulteration in milk using colorimetric detection method is carried out. Findings: Recently there has been great deal of interest of polymer for fabrication of Microfludics devices. One of its great advantage is it does not required clean room process for prototyping of Microfludics chips. In this work we have fabricated and characterize different shapes of channels without clean room process. Experiments to detect Starch in the milk were carried out using the fabricated micro channel. Complete system including micro channel, ardruino microcontroller and TCS3200 colour sensor has been developed to detect the adulteration in milk. Application/Improvements: This system can provide a great platform for fluid analysis and biosensor applications.

Summary
Food is the primary need of human being which plays major sustaining role. The quality food is the need of an hour to stay healthy, live longer and sustain in worst environmental conditions. Polydimethylsiloxane called PDMS or dimethicone is a For detection of this adulteration from food we have been designed PDMS material based channel. It is emerging materials in MEMS for manufacture it has most familiar material for the fast response and reasonable prototyping of microfluidics system[3,4]. That Polydimethylsiloxane (PDMS) have most popular polymer today for reasons of easy fabrication, optical transparency, biocompatibility, robustness, insulating properties and lower Young’s modulus. This incorporation of electronics with microfluidics devices forms a microfluidics system that provides the convenience feature and enables the use of portable application in Biochemical analysis, forensics, and drug delivery applications[5,6]. The device can be automated using color sensors and Arduino board which is discussed in section 5 followed by conclusion
