Introduction

The Department of Biomedical Engineering, SRM University-Delhi NCR, Sonepat, organized an insightful guest lecture on the topic “Can We Replace Animal Testing? The Promise of Organ-on-Chip Technology” on 30 April 2026 at the Conference Hall, Engineering Block. The session was delivered by Dr. Nimisha Roy, Consultant Academics, Regional Centre for Biotechnology (RCB), Faridabad, an expert in the field of biomedical research and emerging healthcare technologies.

The lecture aimed to create awareness among students and faculty about innovative alternatives to traditional animal testing methods used in biomedical research and pharmaceutical development. Dr. Roy highlighted the growing importance of organ-on-chip technology, a cutting-edge microengineering approach that simulates the physiological functions of human organs on miniature devices. The session provided valuable insights into how these systems can improve the accuracy of drug testing, reduce ethical concerns associated with animal experimentation, and contribute to the advancement of personalized medicine and toxicological studies.

Objectives

• To introduce the concept, principles, and scientific foundation of organ-on-chip technology as an emerging alternative to conventional animal testing methods.
• To discuss the limitations, challenges, and ethical concerns associated with the use of animal models in biomedical and pharmaceutical research.
• To explore the capability of organ-on-chip platforms in mimicking human organ physiology and predicting human responses to drugs, chemicals, and toxins under in vitro conditions.
• To highlight the potential of organ-on-chip technology in reducing or replacing animal usage in preclinical testing, toxicology studies, and drug development processes.
• To provide students and faculty members with exposure to recent advancements in bioengineering and human-relevant research models.
