Morphology switch

ADAPTATION to Morphology Switching through COMPONENT SELECTION... 

Morphological switching between nanotube, hexameric receptor and monomers is readily achieved by simple protonation-deprotonation reactions. This system can be described as a library of dynamic, size selective fullerene receptors whose structure... 

Fig. 29 Schematic representation of the proton-driven cyclic morphological switching between NDI monomers, C60 and C70 receptors (the clock indicates the slow kinetics of C60 uptake)...

Another form of switching is well-known in C. albicans. This is the phenomenon of phenotypie switching (Soil 1992) whereby colony morphologies vary dramatieally (e.g. white, opaque, fiizzy, wrinkled.) These may seem trivial to the pharmacist or physician, but the variability extends far beyond the mere appearance of the colonies. It ean eneompass a vast array of bioehemical alterahons, anhgenicities and drug... 

Significant improvements in ECALE deposit morphology and quality were reported as achieved by switching from a thin layer cell to a thick layer H-form cell, integrated in an automated deposition system [46]. Thin epitaxial films of zinc blende CdTe, CdSe, and CdS with predominate (111) orientations were grown. 

Due to the variable appearance of genital warts, treatment maybe based on the size, site, and morphology of the lesions. Additionally, switching to alternate therapy is appropriate if there has been no response after three treatment cycles. 

The diffusion of the charge-compensating counterions through the thin films determines the response time of the systems during redox switching. A more open polymer morphology therefore enhances the ionic mobility and yields a faster response [40].
