Its great to be back in Sydney for the 10th Nanomedicine Conference (10th anniversary year). I presented our work on antibody-based biosensors for EGFR (recently published - congratulations Jiaul!!) and also some new data on cardiac troponin-I. Highlights of Day 1 for included Prof Kanyi Pu (NTU, Singapore) - summarising a fantastic body of work focussing on imaging/sensing applications of semi-conducting polymer nanomaterials which can be used for fluorescence imaging, photo-accoustic imaging, or the amazingly cool "afterglow" imaging.
