Project Title: “Celloidosomes®: A New Paradigm in the Bottom-up Assembly of Multicellular Architectures”______ _______ ________ ____ _______


Samantha developed Celloidosomes®, a cell self-assembly process for bioengineering 3-dimensional tissues in a core-shell structure. Her research focused on demonstrating the vast versatility of the Celloidosome in both composition and applications: from liver repair and reconstruction to biological sensors and neural tissue transplantation, to the “green” biodefense tool for the sequestration of radioactive heavy metals such as Cesium-137.

The ability to build microtissues with a unique core-shell structure solves the oxygen transport limitations of current technologies such as islets and opens the door to virtually endless applications in tissue engineering and organ reconstruction. These Celloidosome units can also be utilized as “smart” bioinks for bioprinting, as each individual unit mimics the larger organ or gland being printed. Additionally, the Celloidosome allows for cell-cell interactions to be further studied so that scientists can gain a better understanding of cell secretions and tumor genesis. The versatility of the Celloidosome allows for its applications to range from 3D tissue repair and reconstruction to, most recently, the use of anisotropic, two-layer bacteria-algae Celloidosome with the capability of acting as a container for the selective sequestration and trapping of radioactive heavy metals, such as Cesium-137.

Samantha is a rising senior at Maggie L. Walker Governor’s School. She plans to study neuroscience in college and pursue a Ph.D. in the field. In 2012, she received the First Place Award in Research from the International Space Olympics competition held in Korolyov, Russia. In 2013 she won, for the third year in a row, the First Place Award (2011 and 2013 Best In Category as well) in Engineering: Materials and Bioengineering at the Intel International Science and Engineering Fair (ISEF). Samantha loves to scuba dive and studies magic and illusions.
