Application of low molecular weight chitosan in animal nutrition, husbandry, and health: A review
Autor: Peter Osei Boamah, Jacqueline Onumah, Mamudu Halidu Agolisi, Frank Idan
Publikováno v: Carbohydrate Polymer Technologies and Applications, Vol 6, Iss , Pp 100329- (2023)
Chitosan (CHT) is a natural substance widely used in veterinary medicine. However, the application of chitosan in animal production has severe shortcomings. This is because it is insoluble in pH ≥ 7 due to its very stable crystalline nature. This h

Gd (III) complex conjugate of low-molecular-weight chitosan as a contrast agent for magnetic resonance/fluorescence dual-modal imaging
Autor: Peter Osei Boamah, Qi Zhang, Jianbo Gong, Mingqing Hua, Yan Huang, Yuzhen Ye
Publikováno v: Carbohydrate Polymers. 143:288-295
The fusion of molecular and anatomical modalities facilitates more reliable and accurate detection in clinic. In this work, we prepared gadolinium (III) complex Gd-DTPA-FITC-CS11 with magnetic resonance (MR) and fluorescence dual-modal imaging modali

A highly selective chemosensor for naked-eye sensing of nanomolar Cu(ii) in an aqueous medium
Autor: Yan Huang, Yaao Qian, Peter Osei Boamah, Qi Zhang, Li Cao, Chunman Jia, Liu Chunling, Qiuyun Yang
Publikováno v: RSC Advances. 5:77965-77972
A novel highly selective and sensitive colorimetric chemosensor L for the detection of Cu2+ ion with a fast response time was designed and synthesized. Receptor L detected Cu2+ ion by changing its color from colorless to magenta in a semi-aqueous sol
