    Stray-capacitance neutralisation for high-resistance microelectrodes—a simple analysis (1981)
    Springer
    Medical & biological engineering & computing 19 (1981), S. 230-236 
    Details
    ISSN: 1741-0444
    Keywords: Electrode resistance ; Neutralisation ; Differentiator ; Bandwidth

    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Abstract The effect of stray-capacitance neutralisation in association with microelectrodes is briefly discussed, together with a simple analysis of the principle of capacitance neutralisation. A common technique is used as an example. An alternative approach is then described where neutralisation is much less dependant on the electrode resistance. This also provides a simple means of determining the magnitude of an equivalent input capacitance, deemed to be the resultant accumulation of distributed stray capacitance. A calibration input is provided to allow the system to be set up easily.

    Cytoplasmic free calcium in single cells of centric diatoms. The use of fura-2 (1987)
    Springer
    Protoplasma 140 (1987), S. 118-122 
    Details
    ISSN: 1615-6102
    Keywords: Cytoplasmic calcium ; Fura-2 ; Diatoms
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Cytoplasmic free calcium concentration has been measured in centric diatoms using Fura-2. Cells hydrolysed Fura-2 acetoxymethyl ester and accumulated free Fura-2 in the cytoplasm. The [Ca2+] distribution in two species (Coccinodiscus concinnus andGuinardia flaccida) has been mapped using digital image analysis.
