Resumo(s): | Electrochemical aptasensors, an emerging technology, enables the detection of protein biomarkers, which may be indicative of tumour activity. Osteopontin is a protein present in body fluids, being a possible biomarker since its overexpression has been related with breast cancer progression. An \RNA\ aptamer, described in the literature, with affinity for human osteopontin, was synthetized, immobilized in a microelectrode gold surface and used for development electrochemical aptasensor for human \OPN\ detection in standard solutions. Cyclic voltammetry results showed that this aptasensor allowed detecting human osteopontin with a detection limit of 8 nM, showing a satisfactory selectivity towards the target in the presence of others proteins, except for thrombin. |
