Quantum dots (QDs) or semiconductor nanocrystals (SNCs) exhibited unique optical and electronic properties, making them distinct from other nanomaterials . QDs show good luminescence properties compared to organic and inorganic nanoparticles . The emission wavelength of QDs can be modified via the changing in QDs' particle size or by selecting a suitable light source for excitation . QDs exhibit a narrow, tunable, and symmetric emission spectrum compared to organic fluorophores . However, QDs with small capping agents tend to aggregate or agglomerate. Thus, large molecules such as biopolymers can be used as stabilizers and capping agents for QDs. The functional groups in the biopolymers can interact with target species such as heavy metal ions offering adsorption and biosensing applications. Several biomolecules were reported to synthesize QDs bioconjugates . However, some of these biomolecules exhibit weak interaction with QDs causing agglomeration or aggregation during the material's separation or under storage as an aqueous solution. Furthermore, preparing these QDs bioconjugates requires complicated procedures and sometimes lacks high reproducibility. The ability to conjugate QDs into biopolymers assemblies such as CTS could create several opportunities for scientific discovery . The surface modification of QDs using biopolymers such as CTS improves the biocompatibility of QDs .
