- grafting amino groups
Examples
-
The synthesized AgNPs were expected to be stabilized by amino groups and robustly immobilized on the fiber surface.
Academic text (2018) -
The preparation procedure of AgNPs-incorporated NH2-CP includes the complexing adsorption of Ag+ onto the amino groups, followed by a facile NaBH4 reduction procedure.
Academic text (2018) -
At the same time, amino groups were chemically grafted onto the paper surface.
Academic text (2018) -
According to previous studies 32 and 34, amino groups can act as complexing centers for silver ions.
Academic text (2018) -
The method of grafting amino groups onto CP was followed as described previously, with a little modification.
Academic text (2018) -
From these results, it was suggested that amino groups were introduced to the CP surface successfully through the silane coupling process.
Academic text (2018) -
Once the metal nuclei were formed during the chemical reduction process, amino groups possibly involved in the nuclei growth stage facilitated the formation of small-sized AgNPs with good distribution.
Academic text (2018) -
The basic nitrogen atom of the amino group has lone pairs of electrons that can bind metal ions to form complexes, thus providing abundant anchoring sites for Ag+ in this study.
Academic text (2018) -
The good recyclability of AgNPs@NH2-CP was attributed to the stabilizing effect of amino groups toward the AgNPs and the enhanced mechanical stability of surface-functionalized CP in water.

Morphology
The term is directly compositional: 'amino' names the –NH2 functional unit and 'group' denotes a bonded assembly or part, so 'amino group' straightforwardly refers to a group characterized by an –NH2 unit. This noun–noun chemical compound follows regular English formation and is used similarly across languages, so a learner who knows both constituents can infer the meaning.
Etymology
Amino group comes from amino, linked to 'ammonia', and group, meaning 'a part', so imagine a tiny piece of ammonia stuck to a larger molecule: a nitrogen atom holding two hydrogen atoms. That's why amino group means the small nitrogen-and-hydrogen part that changes how a molecule behaves.
