monodispersity

monodispersity

[¦män·ō·di′spər·səd·ē]
(organic chemistry)
Polymer system that is homogeneous in molecular weight, that is, it does not have a distribution of different molecular-weight chains within the total mass.

The Ti[O.sub.2] derivatives have several advantages over conventional inorganic fillers, including monodispersity, low density, high thermal stability, and controllable functionalities and have shown potential applications including low-k insulators, sensors, barrier materials, and catalysts.
Along with the chemical nature and composition, properties of the nanoparticles have also been found to be a function of their size, structure, shape, phase, and monodispersity [1].
[20] synthesized AgNPs with different particle size and monodispersity by adjusting the reaction temperature and the flow rate of the precursor solution in the microfluidic device.
As shown in (Figure 4(a)), the [P.sub.VBC-DVB] microspheres prepared by the "one-step seed swelling method" were uniform in size and uniform in dispersion and had good monodispersity. After imprinting, the surface of MIPs (Figure 4(b)) is rough and uneven, with morphological features and uniformly distributed pores, which facilitates the adsorption of molecules on mass transfer.
However, the morphology, size, and surface chemical groups of nanoparticles affect the above mechanisms [61] and our bio-AgNPs lacked monodispersity. According to El-Naggar et al.
It is high-temperature dependent [30] and, therefore, contrary to the temperature required for monodispersity. Schematic diagram for the synthesis, characterization, and in vitro anticancer testing of monodispersed metal nanoparticles is shown in Figure 1.
This type of volume distribution curve reflects the increase in number of dispersed particles and also the increase of monodispersity of solid phase.
More importantly, it was found that all the microstars showed the same structure and morphology (i.e., high monodispersity), which can reinforce all the conclusions derived from the study.
Its other properties like monodispersity, polyvalence, and stability make it an ideal carrier for drug delivery with precision and selectivity.

Unsurprisingly, the use of surfactants seems to improve the monodispersity of the particles when a high quality micelle is formed, as demonstrated by the reduction of halogenated silane aided by phase transfer agents [101,113,117-120].
