The phrase "at specific concentrations" is correct and usable in written English.
It can be used when discussing the precise amounts of a substance in a solution or mixture, often in scientific or technical contexts.
Example: "The experiment was conducted at specific concentrations to determine the effects on cell growth."
Alternatives: "at defined levels" or "at particular amounts".
We present a versatile method for the fabrication of growth factor-loaded scaffolds at specific concentrations.
For unnotched cases, P impurities randomly replace Si atoms at specific concentrations.
Sr at specific concentrations (1 and 2.5 mM) stimulated collagen formation and mineralisation of the hDPSC generated matrix.
Glucosamine sulphate promoted cell proliferation and biosynthesis at specific concentrations and outperformed growth factors in certain instances.
The dipyridyl functionalized polysulfone shows better complexing affinity for nickel ions at specific concentrations of test solutions.
Overall, the results demonstrated that NGO can positively affect the performance of P. major L. calli cells when applied at specific concentrations, and provide useful inputs into the further studies on phytotoxicity assessment of NGO.
Finishes were applied on cotton initially at specific concentration using (a) pad-dry and (b) pad-dry-cure to develop antibacterial activity that would be more durable for antimicrobial performance.
However, P. mirabilis does not show antibacterial activity and E. Coli shows no activity for nanoparticles templated at 1.2 and 1.6% probably because the negative carrier of P. mirabilis and E.coli at specific concentration show less affinity towards titanium metal ions.
Our finding of an independent correlation between NT-proBNP and myocardial perfusion defects (reversible and irreversible) supports that high NT-proBNP levels also could be predictive of reversible respectively irreversible myocardial perfusion defects at specific concentration intervals.
