描述 | 3-Aminobenzoic acid is an intermediate in the synthesis of folate by bacteria, plants, and fungi. A one-pot synthesis of superparamagnetic maghemite-based 4-aminobenzoic acid-coated spherical core-shell nanoparticles (PABA@FeNPs) as suitable nanocomposites potentially usable as magnetic carriers for drug delivery. The products consist of well-dispersed maghemite-based nanoparticles of 13 nm average size that represent an easily obtainable system for delivery of highly cytotoxic cisplatin-like complexes in oncological practice[1]. In addition, PAB (4-aminobenzoic acid) is a safe marker of the completeness of 24 h urine collections. Any collection containing less than 205 out of 240 mg (85%) of PAB, given as 80 mg with each of three meals, is probably incomplete[2]. |

溶解方案 |
DMSO: 80 mg/mL(583.36 mM),配合低频超声助溶,注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO H2O: 4 mg/mL(29.17 mM),配合低频超声助溶 以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂: ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
