Colloidal gold nanoparticles might be of use as nano scale delivery systems of various therapeutic materials in the future. Recent studies have reported the feasibility of colloidal gold nanoparticles as gene delivery systems or protein delivery systems. In this study, we aimed to develop a short-step method useful for screening the optimal coating conditions of colloidal gold nanoparticles with proteins. We observed that colloidal gold nanoparticles have properties of changing its unique color when they were exposed to NaCl solution. Taking advantage of the color changing properties of colloidal gold nanoparticles, we applied the color testing method of colloidal gold nanoparticles solutions for evaluating the protein coating nature. Using bovine serum albumin as a model protein, we tested the protein coating of colloidal gold nanoparticles via the color change upon NaCl addition. The optimal coating concentration and coating conditions of colloidal gold nanoparticles with bovine serum albumin were fixed using the color testing methods. We suggest that the color testing method might be applied to optimize the coating condition of colloidal gold nanoparticles with other therapeutic proteins.

The visual sensory information in physical environments can induce or reduce occupants' stress. In healthcare settings, positive environmental stimulations can promote patient well-being by reducing their stress: poor health environments work against a patient's health. Changing the color in a patient room is an inexpensive process and thus finding better colors for healthcare settings is a cost effective method of improving healing environments. Color may have important implications for pediatric patients, but the investigation of Korean populations has been non-existent. The purpose of this study was to investigate Korean pediatric patients' color preferences for patient room design. The color preferences from 50 Korean pediatric patients were recorded and investigated for gender effects. A simulation method was used because of its reliability and feasibility, allowing for investigating the value of color in real contexts and controlling confounding variables. The overall color preferences from Korean pediatric patients showed that they preferred blue the most and white the least. Gender differences were found in red and purple. Girls preferred red and purple more than boys. The results from this study can help healthcare providers and designers better understand appropriate colors for Korean pediatric patient populations.
