The NanoProduct Lab, also known as the Bedewy Research Group, at the University of Pittsburgh was established by Dr. Mostafa Bedewy in fall 2016.
Our group focuses on fundamental experimental research at the interface between nanoscience, biotechnology, and manufacturing engineering. We make basic scientific discoveries and applied technological developments in the broad area of advanced manufacturing at multiple length scales, aiming at creating novel solutions that impact major societal challenges in areas related to energy , healthcare, and the environment.
We are located in Benedum Hall in the Swanson School of Engineering (SSoE). We are part of the manufacturing group in the Department of Industrial Engineering (IE), and we are also affiliated with the Center for Energy, and the Petersen Institute of NanoScience and Engineering (PINSE).
Research Interests:
Science and technology of nanomanufacturing process development
Nondestructive materials characterization and metrology
Precision design and fabrication of scientific instruments, manufacturing machines, and medical devices
Synthesis and self-organization of nanofilaments, such as carbon nanotubes, and their composites
Bottom-up self-assembly of 2D/3D nanoparticle structures and block copolymers
Patterning of biomolecular systems and biointerfaces
