Dr Amos Danielli, now of Israel’s Bar-Ilan University, developed technology at Tel Aviv University to identify minute quantities of chemicals using magnetic particles attached to fluorescent molecules. One use is to detect the protein Troponin, an indicator of an imminent heart attack. Dr Danielli has founded the company MagBiosense which has won a NIS 900,000 grant from the BIRD foundation.
