    • Gold nanoparticle-based optical nanosensors for food and health safety monitoring: recent advances and future perspectives
    Authors: Nguyen, Ha Anh; Mai, Quan Doan; Ngo, Xuan Dinh; Tran, Quang Huy; Doa,n Quang Tri; Le, Thi Ngoc Loan; Bui, Van Hao; Le, Anh Tuan;  Advisor: -;  Co-Author: - (2022)

    Modern society has been facing serious health-related problems including food safety, diseases and illness. Hence, it is urgent to develop analysis methods for the detection and control of food contaminants, disease biomarkers and pathogens. As the traditional instrumental methods have several disadvantages, including being time consuming, and having high cost and laborious procedures, optical nanosensors have emerged as promising alternative or complementary approaches to those traditional ones. With the advantages of simple preparation, high surface-to-volume ratio, excellent biocompatibility, and especially, unique optical properties, gold nanoparticles (AuNPs) have been demonstrat...
    • Spinel ferrite (AFe2O4)-based heterostructured designs for lithium-ion battery, environmental monitoring, and biomedical applications
    Authors: Pham, Tuyet Nhung; Tran, Quang Huy; Le, Anh Tuan;  Advisor: -;  Co-Author: - (2020)

    The development of spinel ferrite nanomaterial (SFN)-based hybrid architectures has become more popular owing to the fascinating physicochemical properties of SFNs, such as their good electro-optical and catalytic properties, high chemothermal stability, ease of functionalization, and superparamagnetic behaviour. Furthermore, achieving the perfect combination of SFNs and different nanomaterials has promised to open up many unique synergistic effects and advantages. Inspired by the above-mentioned noteworthy properties, numerous and varied applications have been recently developed, such as energy storage in lithium-ion batteries, environmental pollutant monitoring, and, especially, bio...
    • ZnO/ZnFe2O4 nanocomposite-based electrochemical nanosensors for the detection of furazolidone in pork and shrimp samples: exploring the role of crystallinity, phase ratio, and heterojunction formation
    Authors: Nguyen, Tuan Anh; Nguyen, Ngoc Huyen; Ngo, Xuan Dinh; Le, Khanh Vinh; Le, Minh Tung; Nguyen, Thanh Vinh; Nguyen, Van Quy; Vu, Dinh Lam; Le, Anh Tuan;  Advisor: -;  Co-Author: - (2022)

    In this study, we have investigated the influence of crystallinity, phase ratio, and heterojunction formation on the sensing performance of ZnO/ZnFe2O4 (ZnO/ZFO) nanocomposite-based electrochemical sensors for the detection of furazolidone (FZD) antibiotic drug. Results obtained show that the crystallinity and phase ratio of ZnO/ZFO nanocomposites have decisive effects on their electron transfer and active site density. Tuning the crystallinity and ZnO content of ZnO/ZFO nanocomposites is an effective way to enhance the FZD electrochemical sensing performance. Findings from this research suggested that the formation of ZnO/ZFO heterojunction could significantly improve their electroch...
