Characterization Guidelines

IntroductionFTIR identifies surface chemical groups, polymer type, ligand grafting, or contaminants on microspheres.High-Confidence Conditions1.Dry, pure microsphere powder or film ¡ú strong signal, no

IntroductionTEM reveals internal structure, lattice fringes, and particle size at nanometer resolution, especially for microspheres

DODO keep products within their required storage temperature during shipping.All BOT Bioparticles¡¯ microsphere products must be shipped under appropriate temperature conditions as specified in product

IntroductionSEM provides high-resolution images of microsphere surface morphology, size distribution, and aggregation state.High-Confidence Conditions1.Monodisperse, conductive microspheres (e.g., gol

IntroductionZeta potential measures the surface charge of microspheres, a key indicator of colloidal stability and aggregation propensity.High-Confidence Conditions1.Low-conductivity medium (e.g., dei

IntroductionUV-Vis spectroscopy measures optical absorption, surface plasmon resonance (for metal microspheres), or turbidity, and can estimate concentration.High-Confidence Conditions1.Metal microsph

IntroductionDynamic Light Scattering (DLS) measures the hydrodynamic diameter and size distribution of microspheres in suspension by analyzing fluctuations in scattered light caused by Brownian motion
