PEGylation Promotes Hemoglobin Tetramer Dissociation

open access: yesBioconjugate Chemistry, 2009
Hemoglobin conjugated with poly(ethylene glycol) (PEG) acts as an oxygen carrier free in plasma, substituting red blood cells in supplementing oxygen in hypo-oxygenation pathologies. Given the complexity of oxygen delivery controls, subtle structural and functional differences in PEGylated hemoglobins might be associated with distinct physiological ...

Engineering Lipid Nanoparticles for Precision RNA Delivery: Design Principles, Targeting Strategies, and Clinical Prospects

open access: yesCancer Nexus, EarlyView.
ABSTRACT Lipid nanoparticles (LNPs) represent the most clinically advanced platform for RNA delivery and have enabled major breakthroughs in vaccines and gene therapies. However, their broader application is still limited by inefficient extrahepatic delivery, immunogenicity, and insufficient control over tissue‐ and cell‐specific targeting. This review

Polyglycerol‐Based Lipids: A Next‐Generation Alternative to PEG in Lipid Nanoparticles for Advanced Drug Delivery Systems

open access: yesMacromolecular Rapid Communications, EarlyView.
Linear polyglycerol is proposed as a PEG‐alternative in mRNA‐loaded lipid nanoparticles to limit activation of anti‐PEG antibodies and reduce immunogenicity. Resulting nanoparticles may provide similar gene delivery capabilities, while preventing binding of anti‐PEG antibodies compared to PEGylated counterparts.

Arsonic Acid Functional Polymers Enable Stabilization of Iron Oxide Nanoparticles in Aqueous Solution

open access: yesMacromolecular Rapid Communications, EarlyView.
Arsonic acid containing diblock copolymers are developed to incorporate arsonic acid moieties for surface anchoring to IONPs, along with water soluble PEG blocks to impart colloidal stability in aqueous environments. The resulting polymer‐coated IONPs are evaluated for stability in physiological media and cytocompatibility.

A Non‐Antigenic Randomized Polyethylene Glycol/Poly(2‐Phenyl‐2‐Oxazine)‐Based Drug Delivery Platform

open access: yesMacromolecular Rapid Communications, EarlyView.
Randomized PEG (rPEG), a conceptually new PEG alternative, is combined with poly(2‐phenyl‐2‐oxazine) (PPheOzi) to establish an rPEG‐b‐PPheOzi‐b‐rPEG micellar drug delivery platform. The PPheOzi block enables high drug loadings, while competitive ELISA reveals a drastic reduction in anti‐PEG antibody affinity of rPEG in comparison to PEG.

Research advances in the applications of mitochondria‐targeted cyanine dyes in imaging

open access: yesVIEW, EarlyView.
Near‐infrared (NIR) fluorescence imaging, a novel non‐invasive diagnostic tool, plays a crucial role in the imaging and monitoring of solid tumors. At its core are NIR fluorescent dyes, which are widely utilized due to their ability to minimize tissue autofluorescence interference, thereby significantly enhancing the signal‐to‐noise ratio (SNR) and ...
