The phrase "alteration of nanoparticles" is correct and usable in written English.
It can be used in scientific or technical contexts when discussing changes or modifications made to nanoparticles.
Example: "The alteration of nanoparticles can significantly enhance their properties for drug delivery applications."
Alternatives: "modification of nanoparticles" or "change in nanoparticles".
Many studies of nanomaterials make non-systematic alterations of nanoparticle physicochemical properties.
This paper shows alteration of copper nanoparticles bactericidal properties depending on physicochemical characteristics of the particles, dispersive medium, and suspension storage time.
The short-term stability investigation showed no alteration in physicochemical properties of nanoparticles at 4 and 37 °C, but small increase in nanoparticles size was observed after three months of storage at room temperature.
Indeed, using pBR322 plasmids as nano-bioprobes to quantify nano-size damages, we observed that the induction of these alterations is amplified in the presence of nanoparticles (Additional file 1: Figure S2).
For PBHT and the CHF, the most commonly proposed mechanisms are the alteration of the heating surface by deposition of nanoparticles along with the passive/active mode theories.
Our results were in accordance with previous reports which showed that the exposure of nanoparticles causes toxicity and alteration in mitochondrial functioning which may be due to loss in membrane potential [ 37, 46, 47].
Electrostatic interactions dominated at pH 7, while hydrophobic effects were the main force at pH 2. Interestingly, the two sets of binding sites were discriminated by ionic strength at pH 7. The binding of C3G slightly modified the average diameter of NaCas nanoparticles without alteration of its surface charge suggesting a complexation of C3G molecules in the internal casein structure.
Alteration of the heating surface due to deposition of nanoparticles (83.3% of the sample).
Brownian motion combined with the alteration of the heating surface due to deposition of nanoparticles (8.33% of the sample) c.
