An Anarchist Foreign Minister?: The Ideological Background of Rudolf Holsti

Former Finnish Minister of Foreign Affairs, Rudolf Holsti, ended his professional career as a professor at Stanford University. In spring 1941, he encountered a news article on Alexandra Kropotkina and was encouraged to send her a letter. In this letter, Holsti revealed his admiration for her father, "anarchist prince" Pjotr Kropotkin. Holsti’s letter to Alexandra Kropotkina further related that as foreign minister he had even sent food from the Finnish embassy in Moscow to Kropotkin while he was being held in custody by the Soviet authorities. The notion of an anarchist foreign minister is profoundly paradoxical, but the aim of my research is to find Kropotkin’s influences in Holsti's work and publications. Before entering politics, Holsti defended his thesis for PhD at the University of Helsinki in 1913 with a rather anarchist theme, “The Relation of War to the Origin of the State.” My paper and presentation will attempt to answer: how are Kropotkin's ideas present in Holsti's academic work? In addition, Holsti and Kropotkin are case studies who guide my interests in the co-relation between the scientific revolution and social thinking in the 19th century.

CHARACTERIZATION OF ELECTRODEPOSITED POLYANILINE BIOSENSOR PLATFORM FOR ESCHERICHIA COLI O157:H7 DETECTION

Amperometric electrodeposition has been used to obtain uniform, conductive, and repeatable polyaniline (PANi) thin films for use in nano scaled biochemical sensors. This report describes the characterization of these films. Techniques such as ellipsometry were used to test repeatability of the deposition and the uniformity of the deposited thin films. Raman spectroscopy was utilized to confirm the composition of the deposited PANi thin films. Fluorescence microscopy was used to determine the immobilization of antibodies to the PANi thin films using biotin-avidin interactions, as well as the density of active binding sites. Ellipsometry results demonstrated that biomolecules could be immobilized on PANi films as thin as 9nm. Evidence from the Raman spectroscopy demonstrated the conductive nature of the PANi films. The fluorescence microscopy demonstrated that antibodies could be immobilized on PANi films, although the experiment also demonstrated a low density of binding sites. The characterization demonstrates the utility of the PANi thin films as a conductive interface between the inorganic sensor platform and biochemical molecules.
