Organ-on-a-chip a biochip has been created by researchers at cellasys. Researchers are working towards building a multi-channel 3D microfluidic cell culture system that compartmentalizes microenvironments in which 3D cellular aggregates are cultured to mimic multiple organs in the body. Most organ-on-a-chip models today only culture one cell type, so even though they may be valid models for studying whole organ functions, the systemic effect of a drug on the human body is not verified. In particular, an integrated cell culture analog (µCCA) was developed and included lung cells, drug-metabolizing liver and fat cells. The cells were linked in a 2D fluidic
Nominalized adjective Nominalized adjective A nominalized adjective is an adjective that has undergone nominalization, and is thus used as a noun. For example, in "the rich and the poor", the adjectives "rich" and "poor" function as nouns denoting people who are rich and poor respectively. The most common appearance of the nominalized adjective in English is when an adjective is used to indicate a collective group.
