Magnetic Particle-Based Hybrid Platforms for Bioanalytical Sensors

Biomagnetic nano and microparticles platforms have attracted considerable interest in the field of biological sensors due to their interesting physico-chemical properties, high specific surface area, good mechanical stability and opportunities for generating magneto-switchable devices. This review discusses recent advances in the development and characterization of active biomagnetic nanoassemblies, their interaction with biological molecules and their use in bioanalytical sensors

The fiscal crisis and the local state: examination of the structuralist concept

Neo-Marxist theory has been widely used by urban scientists to explain patterns of fiscal stress among US cities during the 1970s. Despite its population, strict empirical tests are rare, and few attempts have been made to account for theoretical and empirical criticism and recent changes in the fiscal behavior of cities. A causal model is developed and tested for long-term debt of large US cities in 1975 and extended through 1985. The results contradict hypotheses of the neo-Marxist theory and show that it ignores the relevance of changes in urban fiscal strategies and underestimates the political flexibility of city managers.
