1
New cards
Biomaterials
Materials designed to interface with biological systems for medical purposes.
2
New cards
Degradation
The process by which a material breaks down or deteriorates, often influenced by environmental conditions.
3
New cards
Surface Properties
Characteristics of the outermost layers of a material that affect how it interacts with its environment, including protein interactions.
4
New cards
Hydrophobicity

The property of being repellent to water; materials with high levels of this do not easily absorb water.

5
New cards
Hydrophilicity

The property of a material to attract water; materials with high levels of this tend to absorb water.

6
New cards
Crystalline Structure
An ordered arrangement of atoms in a material that affects its properties.
7
New cards
Coordination Number
The number of atoms or ions immediately surrounding a central atom in a complex or crystal.
8
New cards
Atomic Packing Factor (APF)
The fraction of the volume of a unit cell that is filled with atoms.
9
New cards
Ionic Bonding
A strong electrostatic bond formed between oppositely charged ions.
10
New cards
Covalent Bonding
A bond formed when two atoms share electrons.
11
New cards
Metallic Bonding
A bond between metal atoms involving a 'sea' of delocalized electrons.
12
New cards
Van der Waals Forces
Weak attractive forces between molecules, important for interactions in biomaterials.
13
New cards
Surface Roughness
A measure of the texture of a surface that can influence biological responses.
14
New cards
Macrophages
A type of immune cell that engulfs and digests cellular debris and pathogens.
15
New cards
Mechanical Properties
Properties that describe a material's behavior under applied forces, such as strength and ductility.
16
New cards
Thermal Conductivity
The ability of a material to conduct heat.
17
New cards
Bioincompatibility
The property of a material that causes an adverse biological response.
18
New cards
Chemical Properties
Characteristics of a material that result in changes to its composition.
19
New cards
Spectroscopy
An analytical technique used to measure the interaction of light with matter to determine material composition.
20
New cards
Amorphous Structure
A non-ordered arrangement of atoms, in contrast to crystalline structures.
