Triethylamine

Triethylamine is a volatile, colorless tertiary amine widely used in chemistry as an organic base, proton acceptor, and reaction reagent. Its nitrogen lone pair binds protons and reacts with acids to form triethylammonium salts; during synthesis, it can neutralize hydrogen halides released in acylation, alkylation, and related transformations. This acid-scavenging action helps drive reactions forward while limiting unwanted protonation of other reactants, and its solubility profile can support straightforward separation from products. Triethylamine therefore serves as a practical tool in organic and medicinal chemistry, although its flammability, strong odor, and corrosive properties require appropriate handling and ventilation.

This work describes the formation of poly(ethylene glycol) (PEG) microgels via a photopolymerized precipitation reaction. Increasing the PEG molecular weight increased microgel diameter and swelling ratio. Simple adaptations to the PEG microgel precipitation reaction are explored for future applications of microgels as drug delivery vehicles and tissue engineering scaffolds.

We describe the preparation of colloidal quantum dots with minimized hydrodynamic size for single-molecule fluorescence imaging. Compared to conventional quantum dots, these nanoparticles are similar in size to globular proteins and are optimized for single-molecule brightness, stability against photodegradation, and resistance to nonspecific binding to proteins and cells.
