• [51]. Briefly, the number of oxygenated surface functional groups is increased first by HNO3 oxidation and quantified by XPS and elemental analysis. Then, the carboxylic acid groups are reacted with SOCl2, before coupling with ethylenediamine. Finally, the pendant amine functions are transformed into

• shapes from sulfur powder [6]. Lim et al. found that copper sulfide dendritic structures could be obtained at high ethylenediamine and low tributylphosphite concentrations by using a copper(I) thiobenzoate (CuTB) precursor [7]. In general, sulfur, Na2S2O3, mercaptan and thiourea are used as sulfur

For comparison, they also altered the carboxyl groups of the native HSA molecule by reacting them with ethylenediamine, thus, converting them into positively charged amino groups, creating an
