Tissue Engineering is that the study of materials that uses the mixture of cells to engineer biologically active molecules to provide well-organized tissues and organs, which can be implanted into the donor with the use of the various engineered methods in conjunction with some physicochemical factors. Biomaterial supports the engineered tissues externally, and guide cells by topographical and chemical signals. Construction of bio artificial tissues in vitro also because the in vivo alteration of cell growth and performance via implantation of suitable cells isolated from donor tissue and biocompatible scaffold materials.
It is the automated generation of biologically functional products with structural organization from living cells, bioactive molecules, biomaterials, cell aggregates like micro-tissues, or hybrid cell-material constructs, through Bioprinting or Bioassembly and subsequent tissue maturation processes.
A formulation of cells suitable for processing by an automatic bio fabrication technology which may also contain biologically active components and biomaterials. cells are the mandatory component of a bioink, and thus, formulations that include biologically active components or molecules, but don't contain any cells, aren't qualified as a bioink.
A material is dispensed through an extruder or nozzle while a computerized arm moves the nozzle to form the 3D shape. This technique is typically combined with a support material that's removed post printing.
