Smart Materials of 21st Century

Smart or intelligent materials are engineered to respond to their environment…These materials are embedded with their own sensors, actuators and control systems that are responsive to presence of light, temperature, pressure or other environmental conditions, and can cause the material surface to change its shape, texture, color or temperature. When engineered at atomic or molecular scale, these materials can be made sensitive enough Continue reading

Nanoparticle based cancer detection system

Knowledge from multiple domains of technology can be applied to create innovative solutions for affordable health care. In my previous week’s post, I wrote about the role that nanoparticles will play in early detection of cancer, by capturing tumor cells from blood stream. The challenge is to characterize fluorescent properties of a blood Continue reading
