Green glyco-conjugated graphene oxides, incorporating mannose and glucose, developed in the design of new antibacterial absorbents. In this context, graphene oxide (GO) was functionalized by ethylenediamine (EDA). Then, the aminated GO (rG-NH₂₎ modified by Glucose (Glu) and Mannose (Man) separately via reductive amination method to fabricate glyco-conjugated GOs known as rG-NH-Glu and rG-NH-Man respectively. The biofunctionalized GOs were characterized by FTIR spectroscopy, X-ray diffraction, Raman spectroscopy, SEM and TGA technique. The glyco-conjugated GOs showed antibacterial activities. The mannose conjugated GOs exhibited higher bactericidal efficiency than GO and rGO-NH-Glu. Moreover, the obtained glyco-conjugated GOs used as absorbent. The results showed that they could effectively remove MB. The maximum adsorption capacity of rGO-NH-Glu and rGO-NH-Man were 100 and 96 mg/g, respectively. Glucose conjugated GOs could remove MB very faster than mannose conjugated ones. Finally, the adsorption kinetics was studied. The results showed that Kinetics data were fitted with the pseudo second order model. Glyco-conjugated GOs could develop new promising materials with enhanced antibacterial activities as well as adsorbent with higher adsorption capacities. The glyco-conjugated GOs could be applied for treatment of polluted waters by pathogenic bacteria and dyes and especially those conjugated with mannose could be considered as potent bacterial targeting agents.

结合了甘露糖和葡萄糖的绿色糖共轭氧化石墨烯，是在新型抗菌吸收剂的设计中开发的。在这种情况下，氧化石墨烯（GO）被乙二胺（EDA）官能化。然后，胺化的GO（rG-NH _2）通过还原胺化方法分别由葡萄糖（Glu）和甘露糖（Man）修饰以制造糖共轭的GO，分别称为rG-NH-Glu和rG-NH-Man。通过FTIR光谱，X射线衍射，拉曼光谱，SEM和TGA技术对生物功能化的GO进行了表征。糖缀合的GO显示出抗菌活性。与GO和rGO-NH-Glu相比，结合有甘露糖的GO具有更高的杀菌效率。此外，所得的糖缀合的GO用作吸收剂。结果表明，它们可以有效去除MB。rGO-NH-Glu和rGO-NH-Man的最大吸附容量分别为100和96 mg / g。葡萄糖结合的GOs去除MB的速度比甘露糖结合的GOs去除MB的速度更快。最后，研究了吸附动力学。结果表明，动力学数据符合拟二阶模型。糖基结合的GO可以开发出新的有前途的材料，具有增强的抗菌活性以及具有更高吸附能力的吸附剂。结合糖的GOs可以用于病原菌和染料对污水的处理，尤其是结合有甘露糖的GOs可以被认为是有效的细菌靶向剂。
