摘要: Semiconductor nanomaterials have found numerous applications in optoelectronic device fabrication and platforms for drug delivery hyperthermia cancer treatment, various other biomedical fields because of their high photochemical stability size-tunable photoluminescence (PL). However, little attention has been paid to exploring the energetics formation these semiconductor nanoparticles. We demonstrate that nanocrystals with biofunctionalization supported by widely used groups, BSA cysteine, is an exothermic spontaneous process driven enthalpy. The whole reaction shows smaller particles favored lower synthesis temperature. Further, it shown thermodynamics nanoparticle strongly influenced conformation protein matrix. also thermodynamically more favorable compared involving organic thiol groups. enthalpy compensates unfavorable entropy, resulting Gibbs free energy. Thus, this study can open up new avenues establishing a thermodynamic basis design nanosystems tunable properties.
