Prof. Gorachand Dutta

IIT Kharagpur
Prof. Gorachand Dutta, PhD is an Assistant Professor with the School of Medical Science and Technology, Indian Institute of Technology Kharagpur. His research interests include the design and characterization of portable biosensors, biodevices and sensor interfaces for miniaturized systems and biomedical applications for point-of-care testing. He received his Ph.D in Biosensor and Electrochemistry from Pusan National University, South Korea, where he developed different class of electrochemical sensors and studied the electrochemical properties of gold, platinum, and palladium based metal electrodes. He completed his Post-doctoral fellowships in the Department of Mechanical Engineering, Michigan State University, USA and Department of Electronic and Electrical Engineering at University of Bath, UK. During his research tenure in USA and UK, Prof. Dutta invented an enzyme- free, disposable miniaturized immunosensor chip using micropatterned electrode and wash-free method for the development of mobile phone-based platforms for fast and simple point-of-care testing of infectious and metabolic disease biomarkers. He has expertise on label-free multichannel electrochemical biosensors, electronically addressable biosensor arrays, aptamer- and DNA-based sensors and surface bio-functionalization. Also his focused areas: (1) integration of biosensors with fuel cell for self-powered biodevices, (2) low-cost, fully integrated biosensor devices using Lab-on-Printed Circuit Board (PCB) approach, (3) enzyme based immunosensor (ELISA), (4) ultra-sensitive biosensors using magnetic bead assays, nanoparticles, CNT, dendrimer, (5) Lab-on-a-Chip devices for biomedical diagnostics, (6) bio-nanotechnology for drug delivery, (7) microfluidics.

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 30 April 2023 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.


Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.
