A biomaterial is a substance that has been engineered to interact with biological systems for a medical purpose – either a therapeutic (treat, augment, repair, or replace a tissue function of the body) or a diagnostic one. The corresponding field of study, called biomaterials science or biomaterials engineering, is about fifty years old.
The Draw-A-Scientist Test (DAST) is an open-ended projective test designed to investigate children's perceptions of the scientist. Originally developed by David Wade Chambers in 1983, the main purpose was to learn at what age the well known stereotypic image of the scientist first appeared.

Bioinstructive materials provide instruction to biological cells or tissue, for example immune instruction when monocytes are cultured on certain polymers they polarise to pro- or anti-inflammatory macrophages with potential applications in implanted devices, [1] [2] or materials for the repair of musculoskeletal tissues.

A biomaterial is any matter, surface, or construct that interacts with living systems. As a science, biomaterials is about fifty years old. The study of biomaterials is called biomaterials science or biomaterials engineering. It has experienced steady and strong growth over its history, with many companies investing large amounts of money into ...
Biomimetic materials in tissue engineering are materials that have been designed such that they elicit specified cellular responses mediated by interactions with scaffold-tethered peptides from extracellular matrix (ECM) proteins; essentially, the incorporation of cell-binding peptides into biomaterials via chemical or physical modification. [3]
The ideal cell response to a bioactive surface is characterized by biomaterial stabilization and integration, as well as the reduction of potential bacterial infection sites on the surface. One example of biomaterial integration is a titanium implant with an engineered biointerface covered with biomimetic motifs. Surfaces with these biomimetic ...
The Heaf test, a diagnostic skin test, was long performed to determine whether or not children had been exposed to tuberculosis infection. The test was named after F. R. G. Heaf . Also known as the Sterneedle test , [ 1 ] it was administered by a Heaf gun (trademarked "Sterneedle"), [ 2 ] a spring-loaded instrument with six needles arranged in ...
