Business Wire

NOKOMIS, Fla. -- July 23, 2013

In a successful bid to introduce its groundbreaking 3D cell culturing
technology to a budding generation of “MAD” scientists, Rainbow Coral Corp.
(OTCBB: RBCC) partner Nano3D BioSciences (n3D) has announced the winners of an
intriguing scientific discovery competition, The MAD Scientist Contest by n3D.

The top cash prize was awarded to Hamsa Jaganathan, Ph.D., of the Methodist
Hospital Research Institute for her amazing model of a breast tumor
microenvironment, created by co-culturing breast cancer cells and fibroblasts.
Second prize went to Matthew Hogan at the University of Houston for his
creation of a functional, or beating, primary cardiac cultures in vitro.

“The winning entries illustrate how 3-D, suspended cultures constructed using
n3D technology improve data and achieve results impossible with other
cell-culturing systems,” said RBCC CEO Patrick Brown. “The MAD Scientist
Contest also served to introduce n3D's Bio-Assembler system to the young
scientists who will undoubtedly lead cellular research into the future.”

This contest is a critical piece of n3D and RBCC's strategy to build strong
interest in the Bio-Assembler among researchers across a broad spectrum of
scientific and research disciplines. The system's revolutionary functionality
allows it to produce accurate, 3D representations of in vivo tissues faster
and easier than any other existing technology.

RBCC formed a biotech subsidiary,RainbowBioSciences, to market and develop
new medical and research technology innovations to compete alongside companies
such asBristol Myers Squibb Co.(NYSE:BMY),Biogen Idec Inc.
(NASDAQ:BIIB),Abbott Laboratories(NYSE:ABT) and Amgen
Inc.(NASDAQ:AMGN).Rainbow BioSciences acquired an equity interest in n3D
earlier last year.
