BIOSEPARATION Meaning and
Definition
-
Bioseparation refers to the process or technique of separating, purifying, or isolating biological substances or molecules from complex mixtures. It is a critical step in various fields of life sciences, including biotechnology, pharmaceuticals, food and beverage, and environmental science. The goal of bioseparation is to selectively and efficiently separate a desired substance or component from a mixture, while minimizing damage or contamination to the target molecule.
In bioseparation, various methodologies are employed, such as centrifugation, chromatography, filtration, electrophoresis, and extraction, among others. These methods are designed based on the physical, chemical, or biological properties of the molecules to be separated, such as size, charge, hydrophobicity, solubility, and affinity. The choice of method depends on the specific application and the nature of the substances being separated.
Bioseparation is used for a wide range of purposes, including the isolation and purification of proteins, nucleic acids, carbohydrates, peptides, cells, and viruses. It is essential for laboratory research and development, as well as large-scale industrial production. The efficient separation of biomolecules is crucial for downstream processing, as it allows for analysis, characterization, and subsequent formulation or application of the target substance.
The advancement of bioseparation techniques has greatly impacted the fields of medicine, biotechnology, and biopharmaceuticals, facilitating significant progress in the diagnosis, treatment, and production of therapeutic agents. It plays a fundamental role in the manufacturing of biopharmaceuticals, vaccines, enzymes, and recombinant proteins, enabling the purification and concentration of these biomolecules to desired levels of purity.
Etymology of BIOSEPARATION
The word "bioseparation" can be divided into two parts: "bio" and "separation".
The prefix "bio" comes from the Greek word "bios", meaning "life". It is commonly used to refer to living organisms, biological processes, or anything related to biology.
The word "separation" comes from the Latin word "separare", which means "to divide" or "to part". It is derived from the prefix "se-", meaning "apart", and the verb "parare", meaning "to prepare" or "to arrange".
Therefore, the etymology of "bioseparation" implies the division or separation of biological entities or components. In the context of biotechnology or bioengineering, bioseparation refers to the process of separating specific biological molecules, cells, or organisms from complex mixtures for various applications such as purification, analysis, or production.
