  2. Biotransducer - Wikipedia

    en.wikipedia.org/wiki/Biotransducer

    Biosensors based on type of biotransducers. A biotransducer is the recognition-transduction component of a biosensor system. It consists of two intimately coupled parts; a bio-recognition layer and a physicochemical transducer, which acting together converts a biochemical signal to an electronic or optical signal.

  3. Bio-FET - Wikipedia

    en.wikipedia.org/wiki/Bio-FET

    Bio-FETs couple a transistor device with a bio-sensitive layer that can specifically detect bio-molecules such as nucleic acids and proteins. A Bio-FET system consists of a semiconducting field-effect transistor that acts as a transducer separated by an insulator layer (e.g. SiO 2) from the biological recognition element (e.g. receptors or probe molecules) which are selective to the target ...

  4. Biosensor - Wikipedia

    en.wikipedia.org/wiki/Biosensor

    The main requirements for a biosensor approach to be valuable in terms of research and commercial applications are the identification of a target molecule, availability of a suitable biological recognition element, and the potential for disposable portable detection systems to be preferred to sensitive laboratory-based techniques in some ...

  5. Cell cycle - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle

    The cell cycle, or cell-division cycle, is the sequential series of events that take place in a cell that causes it to divide into two daughter cells. These events include the growth of the cell, duplication of its DNA ( DNA replication ) and some of its organelles , and subsequently the partitioning of its cytoplasm, chromosomes and other ...

  6. Biochip - Wikipedia

    en.wikipedia.org/wiki/Biochip

    3D Sarfus image of a DNA biochip. The microarray—the dense, two-dimensional grid of biosensors—is the critical component of a biochip platform. Typically, the sensors are deposited on a flat substrate, which may either be passive (e.g. silicon or glass) or active, the latter consisting of integrated electronics or micromechanical devices that perform or assist signal transduction.

  7. Optogenetic methods to record cellular activity - Wikipedia

    en.wikipedia.org/wiki/Optogenetic_methods_to...

    Optogenetics began with methods to alter neuronal activity with light, using e.g. channelrhodopsins.In a broader sense, optogenetic approaches also include the use of genetically encoded biosensors to monitor the activity of neurons or other cell types by measuring fluorescence or bioluminescence.

  8. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    Mitotic cell division enables sexually reproducing organisms to develop from the one-celled zygote, which itself is produced by fusion of two gametes, each having been produced by meiotic cell division. [5] [6] After growth from the zygote to the adult, cell division by mitosis allows for continual construction and repair of the organism. [7]

  9. Bioinstrumentation - Wikipedia

    en.wikipedia.org/wiki/Bioinstrumentation

    An imaging system is a system that creates images of various parts of the body depending on what is needed to be analyzed. the system is used to diagnose conditions before they become too serious. Some examples of imaging systems include x-rays, computed tomography (CT scan), magnetic resonance imaging (MRI), and ultrasound.
