Refractive Index Matched PMMA Colloids

Check if the same lab product or an alternative is used in the 5 most similar protocols
We suspend Nile Red–dyed PMMA colloids and polyhydroxystearic acid polymer–grafted PMMA colloids in a mixture of cis-decahydronaphthalene and tetrachloroethylene (Sigma-Aldrich), whose refractive index and density are closely matched with those of particles, inside a glass capillary. The PMMA particles have diameter σ = 1.8 μm, with the polydispersity of less than 2.5%. The colloidal particle volume fraction ϕ is around 54%. We find that adding 50 mM/liter dioctyl sulfosuccinate sodium salt (Sigma-Aldrich) to the system largely screens surface charges on particles, which allows us to regard the system as hard-sphere like. The other experimental procedures are the same as the charged colloidal systems.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
