The phrase "as a small particle" is correct and usable in written English.
It can be used in scientific or descriptive contexts to refer to something that is being compared to or described as a small particle.
Example: "The substance dispersed in the air as a small particle, making it difficult to detect with the naked eye."
Alternatives: "like a tiny particle" or "in the form of a small particle."
For this purpose, we design the suspensions using two kinds of polystyrene beads (PS, size ∼530 nm) as a large particle which are electrostatically stabilized and are different in surface properties only, while keeping unstable alumina coated silica (Al-silica, size ∼12 nm) as a small particle.
Thus, TAT-pK/DNA complexes possess the necessary elements for transfection as a small particle, although the efficiency is lower than that of adenoviral vectors.
As we know, a small particle size always means high specific surface area.
The sample prepared from Na4P2O7 had a small particle size as indicated in the SEM image (Fig. 2d); however, large particle sizes were observed in the particle size distribution analysis (Fig. 3d).
In addition, the permeable void ratio and absorption after immersion ratio were decreased as a smaller particle size of fly ash such as Spherix 15 (4.78 µm) was used.
"You can characterize the Leahy as having a smaller particle range," one official said.
As a result, the autocorrelation function, describing the similarity between the two signals, will be greater for particles with a larger hydrodynamic radius, i.e., the signal from a larger particle will not have altered as much over time as that from a smaller particle.
As NPs featured a smaller particle size and a high surface area, they could enter the blood circulation via the capillaries and pass through the endothelial cell gap and migrate to the tumor site, thus achieving a drug-targeted distribution and enhancing the bioavailability of the drug.
Non-porous magnetic microparticles feature a good superparamagnetic separation characteristics, as well as a relatively small particle size of approximately 1 μm, which makes them less prone to mass transport limitations [ 2].
As the alternative cementitious material possesses a smaller particle size and greater fineness modulus as compared to that of the OPC, therefore, it is assumed that the alternative cementitious material would expose a greater surface area for the hydration reaction, which may lead to developing the early strength.
Electrochemical impedance spectroscopy showed that electrons in NHS ZnO with a larger particle size have a longer electron lifetime than NHS ZnO with a smaller particle size, as the latter hinders the electron transport in the NHS ZnO nanostructured films.
