Abstract: A reaction cell for an automated peptide synthesizer consists of a body having a first reaction well in fluid communication with a second reaction well for simultaneous reactions. The first reaction well can be used for reagent pre-activation simultaneously with an amino acid addition in the second reaction well. When the addition reaction is complete and after a washing step the activated reagent is automatically transferred to the second reaction well for the next addition reaction without the necessity of a separate transfer step.
Abstract: A method for capturing small objects in a confined space such as an artery or duct in a body by bringing an elongated flexible body having a distally disposed operative head provided with a plurality of nanostructures into proximity with the object. When in proximity intermolecular forces are created between the nanostructures and the object that attract the object to the operative head. By application of high frequency electrical current the nanostructures act as electrical knives to cut away or cauterize an object.
