The pharmaceutical market has largely been dominated by small molecule drugs; however, larger biomolecules have recently become important contenders. Of these biomolecules, protein and peptide therapeutics are proving useful due to their often improved pharmacokinetic properties. In many circumstances, functionalisation…

Alzheimer’s (AD) and Parkinson’s (PD) diseases are neurodegenerative diseases presently without effective drug treatments. AD is characterized by general cognitive impairment, difficulties with memory consolidation and retrieval, and with advanced stages episodes of agitation and anger. AD is increasing in…
