The phrase "attach positively" is correct and usable in written English.
It can be used in contexts where you are instructing someone to connect or affix something in a positive manner, often in technical or instructional writing.
Example: "To ensure a secure connection, make sure to attach positively the wires to the terminal."
Alternatives: "connect securely" or "fasten firmly".
We attempt to mimic the structure of μ-conotoxin by (1) replacing its bulky core with a C84 fullerene and (2) chemically attaching positively charged groups to the fullerene surface.
We first covalently attached positively charged (RRRRR), neutral (AAAAA), hydrophobic (FFFF), and negatively charged [DE pCAP LI] peptides to cFΦR4 (Table 1, compounds 5 8, respectively).
A strategy to overcome this problem is to attach a positively charged virtual particle to the halogen.
This could further be explained based on the assumption that in the presence of NO3 −, the negatively charged NO3 − would attach to positively charged surface.
Proton directly attached to positively charged nitrogen atom is highly deshielded and hence resonates in the low field, δ 8.76, as a broad singlet peak.
These characteristics were explained by the effective role of occupying the oxygen defects on the surface of TAG Ce3+colloidal nanocrystal because the amphoteric LDA molecules were attached by positively charged TAG Ce3+colloidal nanocrystals.
The results show that HA is strongly attached on NS positively charged by cationic surfactant.
Anionic cyclodextrin was attached to the positively charged AuNPs/PEI nanoparticles by ionic bonds.
The qualitative analysis of the structure activity relationships (SAR) revealed the importance of a long methylene middle chain of at least 8 methylene groups between the two bisquaternary naphthalimides or a monoquaternary naphthalimide consisting of a long alkyl chain attached to the positively charged nitrogen atom.
The shift in the isoelectric point is due to the fact that the negatively charged carboxylic groups dissociated from the dispersant are attached on the positively charged nanoparticle surface, based on the electrosteric stabilization effect, respectively [57].
