m-PEG4-benzaldehyde

m-PEG4-benzaldehyde is a small molecule PEG linker containing a terminal benzaldehyde moiety that can react with primary amine groups. PEG4 armr increases the solubility of compounds in aqueous media.

m-PEG4-Benzaldehyde is used in the development of biotin-decorated NIR-absorbing nanosheets for targeted photodynamic cancer therapy
