Early diagnosis is crucial for inter -vention to improve outcomes. The current positron emissiontomography (PET)-imaging and cerebrospinal fluid biomarkermethods typically recognize amyloid pathology following grossneurodegeneration and limit their usage for identification inasymptomatic phases[1] . This warrants the need to buildsensi -tive and specific tools forthe early detection of such a disease -like condition.  \nQuantum protein probes are nanoscale agents that employquantum mechanical properties for biomolecular detection.They are specifically quantum dot (QD)-based probes, whichare highly popular and progressive in the aspect of a tool forearly amyloid detection. QDs are semiconductor nanocrystalswith exclusive optical properties, namely size-tunable fluores -cent emission and exceptional photostability, allowing highlysensitive detection of amyloid aggregates. Unlike conventionalamyloid dyes, such as thioflavin T, QD-based probes have theadvantage of selective binding to neurotoxic species, namely,amyloid-beta (Aβ) monomers and oligomers, before fibril for -mation, thus providing insight into the pre-symptomatic diseasestate[2,3] . The process forms a binding event involving surfacechemistry, hydrophobic interaction, and structure-specificrecognition, followed by an increase in selectivity against amy -loid species. Furthermore, differing amyloid strain types showdistinctive fluorescence signaturesand, subsequently, this couldhelp determine an accurate diagnosis in a variety of amyloido -pathies, as different strains may associate with different trajec -tories of disease progression[3,4] .  \naDepartment of Medicine, King Edward Medical University, Lahore, Pakistan,bDepartment of Medicine, Jinnah Sindh Medical University,Karachi, Pakistan andcDepartment of Medicine, The Maldives National University, Malé, MaldivesSponsorships or competing interests that maybe relevant to content are disclosedatthe end of this article.  \n*Corresponding author.
