Precision Polymer develops and manufactures single-molecular-weight precision polyethylene glycol (PEG) and its derivatives, precision PEG lipids, precision polyethers and polyesters, and high-performance precision polymers at scale. These materials serve applications in pharmaceutical excipients, nanomedicine, nucleic acid delivery, high-performance resins, and advanced electronic chemicals. Drawing on its expertise in precision polymer synthesis, analytical characterization, and functional evaluation, the company offers the following testing and evaluation services to research institutions and industry clients:
1. Molecular Structure and Composition Analysis
We use chromatography, spectroscopy, mass spectrometry, and other analytical techniques to characterize chemical structure, molecular weight and its distribution, end groups, degree of polymerization, monomer composition, sequence, and purity.
2. Characterization of Nanoassemblies and Biointerfaces
We analyze nanoparticles, self-assembled structures, and aggregates for particle size and size distribution, morphology, encapsulation efficiency, surface coverage, and particle-to-particle uniformity and heterogeneity. We also characterize the composition and structure of the protein corona at the nano–bio interface.
3. Functional Testing and Application Performance Evaluation
We test material assembly behavior, surface and interfacial properties, and performance in applications such as drug delivery, medical imaging, and micro- and nanofabrication.
