• °). Attaching biomolecules to the surfaces lowers the contact angle to values of approximately 20° proving that the hydrophobicity/hydrophilicity of the substrates is a constant parameter in the following cell experiments. The potential of the substrates to support neural cell adhesion was tested with SHSY5Y

• rim, the peristome, for initial prey capture due to its specific microstructure combined with both surface hydrophilicity and secretion of hygroscopic nectar, was recently discovered [8][9][10][11]. In addition, the digestive fluid collected in the lower part of the pitcher was recently found to be

• , in an absolute sense, be considered hydrophilic [11]. That work also discussed why for a partially wetting droplet to be observed there is necessarily an assumption of some rigidity of the substrate, so that the usual definition of relative hydrophobicity (and relative hydrophilicity) through contact

• chemistry, will adhere to the water-air interface; a similar conclusion to that regarding the absolute hydrophilicity of solids when their curvature energy is zero. The effect of surface chemistry, characterised through the Young’s law contact angle, is to determine the strength of the adhesion to the air

Empirically, however, in order to obtain stable spherical micelles, the block length of PS, x, should be significantly larger than the PVP length y
