<p>Hi:</p><p>The attached file contains one article, one supporting material associated with the first article, and the second article. The first article titles with "Cu<sup>2+</sup> functionalized N-acetyl-L-cysteine capped CdTe quantum dots as a novel resonance Rayleigh scattering probe for the recognition of phenylalanine enantiomers". The second article titles with "A novel and sensitive turn-on fluorescent biosensor for the determination of thioctic acid based on Cu<sup>2+</sup>-modulated N-acetyl-L-cysteine capped CdTe quantum dots"<br /><br />Could you please help me to check the spelling, grammar, punctuation, consistency/appropriateness of verb tenses, transitional phrasing, continuity/flow of thoughts, and support of statements? Any other comments and feedbacks are highly appreciated.</p> Thanks a lot!
