Abstract :
Forming process of liposome droplet and its stable immobilization on a Si-based microbolometer are investigated and applied for detection of causative protein of Alzheimer´s disease, amyloid ß (Aß) protein, where the disease is closely related to the amyloid fibril formation. This work is a preliminary but innovative approach applying a bio-thermochemical microsensor to monitor the formation. It is observed that the bolometer surface keeps a long time intact behavior of the liposome up to 24 hours. It seems from time course results with Aß that the variation in the temperature profile corresponds to that observed in fluorescence analysis result of the formation.
