The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the properties that they exhibit. Additionally,...

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Polymeric materials are widely used in civil structures, with uses ranging from very soft sealants to more rigid pipes in water and wastewater systems. The most basic definition of a polymer is a molecular structure with repeating subunits. The term polymer comes from Greek, where "poly" means many, and "-mer" means basic unit. Monomers, or single mers, are the specific repeating units. With...

This video demonstrates a method for fabricating polymer microbeads that encapsulate neurotoxic amyloid-beta-secreting cells. The cell-polymer suspension is processed through a microbead fabrication device, with polymer gelation achieved via calcium cross-linking, forming spherical microbeads around the cells. The polymer allows cell proliferation while allowing controlled, long-term amyloid-beta release, simulating its accumulation in Alzheimer's disease.

Here, we describe protocols for the preparation of trans-cyclobutane fused cyclooctenes (tCBCO), their polymerization to prepare depolymerizable olefinic polymers, and the depolymerization of these polymers under mild conditions. Additionally, protocols for the preparation of depolymerizable networks and compression molding of rigid linear plastics based on this system are described.
FAQs
Surface properties help determine which proteins adsorb when the material contacts biological fluids. That adsorption can affect subsequent cellular interactions and influence whether tissues tolerate the material. Chemists therefore adjust polymer composition and processing to control the surface presented to cells and fluids, which is especially important for devices and implants that remain in close biological contact.
Molecular weight and degradation behavior affect how a polymer changes during use and what products it releases. Those products can influence biological compatibility, while the rate and extent of degradation help determine whether the material remains functional for the intended period. Controlling these variables is therefore central to designing polymers for drug delivery, scaffolds, and implants.
Polymer composition provides a way to balance flexibility, strength, permeability, and biodegradability. Changing the chemical makeup can alter how the material interacts with proteins and cells as well as how it behaves physically. This tuning allows chemists to match a material's properties to a biomedical role rather than treating compatibility as a single, isolated characteristic.
No. Biodegradability describes how a material breaks down, whereas compatibility also depends on chemical structure, surface properties, molecular weight, protein adsorption, and cellular interactions. Degradation products are relevant because their release can affect biological responses. Consequently, a polymer must be considered as a complete chemical and biological system, not judged by degradability alone.
Development begins by matching the intended biological contact and function with suitable chemical structure and processing conditions. Chemists then tailor composition and processing to control flexibility, strength, permeability, biodegradability, and surface behavior. Considering these factors together helps produce a material whose physical performance and interactions with proteins, cells, and biological fluids fit the proposed application.
In drug-delivery systems, polymer properties can be tailored to support the material's role in contact with biological fluids and tissues while controlling relevant physical behavior. Permeability, degradation, and composition are particularly important design considerations because they influence how the system functions over time. The same chemical principles connect material compatibility with effective biomedical delivery.
Tissue-engineering scaffolds and implants require materials that provide useful physical properties while minimizing harmful biological responses. Flexibility and strength can support structural requirements, whereas surface properties and chemical structure influence protein adsorption and cellular interactions. Degradation behavior also matters when the material is intended to change in the biological environment, linking polymer chemistry to tissue-focused design.
They connect polymer chemistry with biomedical research by showing how molecular design, processing, and material properties affect biological performance. Research can examine relationships among chemical structure, surface behavior, degradation, protein adsorption, and cellular response. These connections support the development of safer and more effective materials for medical devices, drug delivery, tissue engineering, and implants.
