Circulatory half-life is a key success factor for new drugs. In this respect, PEGylation or PEG-ing—the modification of potential candidates ranging from non-peptidic small molecules to peptides and proteins, antibody fragments, aptamers, and saccharides or oligonucleotides with polyethylene glycol chains—offers numerous advantages.

Kanjiro Miyata (The University of Tokyo, Japan) provides insights on the rational design of polymeric materials for “smart” oligonucleotide delivery.

Prof. Randal Lee discusses iron oxide magnetic nanospheres and nanocubes design considerations for biosensing applications.
