Alzheimer's Disease (AD) is one of the most common causes of dementia and is predicted to affect more than 130 million people by 2050. . The economic cost incurred because of caring for AD were estimated to be USD 600 billion annually. The development of AD has been linked to the presence of abnormal contents of β-amyloid peptides (Aβ) in the brain, which forms neurotoxic dimers, oligomers and plaques as a result of aggregation. To date, the most studied amyloid is Aβ(1-x) (where x refers to 16, 40 or 42 amino acids). However, according to analytical studies, Aβ(4-x) is a major component of plaques, often more prevalent than Aβ (1-x). For this reason, Aβ(4-x) is currently being widely studied. The use of electrochemical methods has become a complementary tool in biochemical studies related to the detection, characterisation and kinetic studies of Aβ peptide aggregation. Cyclic voltammetry (CV), differential pulse voltammetry (DPV) and square wave voltammetry (SWV) are the most commonly used, fast and easy electrochemical techniques to study this processes through the oxidation processes of amino acids present in the peptide chain. Of all the amino acids present in the Aβ chain, only three are redox active: histidine (His, H), methionine (Met, M) and tyrosine (Tyr, Y). The changes in voltammetric behaviour related to peak position and current decrease of the peaks corresponding to the oxidation of tyrosine, histidine and methionine allow for investigation of fibrilisation mechanisms not only of full-length Aβ, like Aβ (1-40) and Aβ (1-42) but also shorter fragments (like Aβ (10-20), Aβ (12-28)) or mutants (e.g.
