In experiments, when the color of magnetic beads gradually changes from brown to reddish-brown, many people may wonder: can these magnetic beads still be used? In fact, the discoloration of magnetic beads is a common phenomenon with certain scientific principles behind it. I.Reasons for Magnetic Bead Discoloration Magnetic Silica beads commonly [...]
1. Particle Aggregation Causing Measurement Errors PSL particles tend to aggregate in solution due to van der Waals forces or electrostatic interactions, leading to overestimated particle sizes and compromised calibration accuracy. Solutions: Pre-use dispersion: Ultrasonicate for 10-15 min (power ≤50W) to break aggregates. Surfactant addition: Incorporate 0.01% Triton X-100 in dilution [...]
Fluorescence imaging technology, as a vital tool in biomedical research, plays a key role in fundamental life science research, preclinical medical studies, and drug development due to its minimal tissue damage, absence of harmful electromagnetic radiation, and low-cost imaging equipment. With the rapid advancement of nanotechnology, fluorescent nanomaterials have emerged [...]
PMMA microspheres, or polymethyl methacrylate microspheres, are polymerized from methyl methacrylate (MMA) monomers. Their unique properties enable widespread applications across numerous fields. 1.Characteristics of PMMA Microspheres (1) Optical Transparency PMMA microspheres exhibit exceptional optical transparency, with high light transmittance and minimal light scattering. This makes them ideal for optical applications, [...]
During experiments, when the color of magnetic beads changes from brownish to reddish-brown, many people may wonder: Can these magnetic beads still be used? In fact, discoloration of magnetic beads is a common phenomenon with underlying scientific principles. Understanding these principles allows for a more confident approach to handling the [...]
