Bio-inks are materials used to produce engineered/artificial live tissue using 3D printing. These inks are mostly composed of the cells that are being used, but are often used in tandem with additional materials that envelope the cells. The combination of cells and usually biopolymer gels are defined as a bio-ink.

At their core, bioinks are material substances infused with live cells that, when deployed in a bioprinter, allow for the construction of three-dimensional structures mimicking natural tissues. These biomaterials are crucial to the successes of 3D cell culture, and their formulation can greatly influence the overall results of this process.

During the bioprinting process, a solution of a biomaterial or a mixture of several biomaterials in the hydrogel form, usually encapsulating the desired cell types, termed the bioink, is used for creating tissue constructs.

2017年3月1日 · This paper discusses “bioink”, bioprintable materials used in three dimensional (3D) bioprinting processes, where cells and other biologics are deposited in a spatially controlled pattern to fabricate living tissues and organs.

One of the most important components of 3D bio-printing is the bio-ink, which is a mixture of cells, biomaterials and bioactive molecules that creates the printed article. This review describes all the currently used bio-printing inks, including polymeric hydrogels, polymer bead microcarriers, cell aggregates and extracellular matrix proteins.

2018年5月1日 · During the bioprinting process, a solution of a biomaterial or a mixture of several biomaterials in the hydrogel form, usually encapsulating the desired cell types, termed the bioink, is used for creating tissue constructs.

Bioinks contain living cells and biomaterials that mimic the extracellular matrix environment, supporting cell adhesion, proliferation, and differentiation after printing. In contrast to tradtional 3D printing materials, bioinks must have:

Bio-inks are printable materials that can incorporate live cells in 3D and bioactive molecules for bioprinting, allowing for precise 3D placement of cells or molecules within the construct. Bio-ink 3D-printing is a single step method to develop cellularized scaffolds.

2023年3月31日 · Bioink, the primary ingredient in 3D bioprinting, is the most recent development in tools for tissue engineering and regenerative medicine [4]. 3D bioprinting is heavily reliant on bioinks, biomaterials, and cells utilized in the creation of 3D cultures [5].

2018年4月6日 · Combination of different methods and enhancements in properties are required to develop more successful bioinks for the 3D printing of organs or tissue structures. This review consists of the recent state-of-art of polymer-based bioinks used in 3D printing for applications in tissue engineering and regenerative medicine.
