We have previously shown that hemispherical soft fingertips are at equilibrium when they are in contact with objects, suggesting that the contact force and flexibility of these soft fingertips are important for stable grasping and manipulation. Hence, by making use of these characteristics, soft fingers can manipulate objects dexterously. While our previous(More)
We have previously shown that a hemispherical soft fingertip is in equilibrium when it is in contact with an object. The characteristics of the contact force and flexibility of a soft fingertip are important in stable grasping and manipulation. Hence, using these characteristics soft fingers can manipulate objects dexterously. We previously focused on a(More)
The application of the thin-agar-layer coated filter culture technique (Z. Naturforsch. 42c, 1082 (1987)) has been extended to the detection of ester hydrolysis and 2-hydroxyacid oxidation by microbial colonies. The former was performed by spraying with bromocresol purple and the latter with a salicylhydrazide reagent. Under the optimized conditions, the(More)
Not less than 1 nmol of methionine and phenylalanine were detected as fluorescent spots on agar plates with o-phthalaldehyde reagent under UV light. Microorganisms were grown on thin-agar-layer coated filter papers placed on nutrient agar plates, and then transferred onto new plates lacking nutrients by moving the papers. After the background amino(More)
