“…In particular, the obtained HNT-chitosan film could promote the direct electrochemistry of HRP and catalyze the reduction of H 2 O 2 . 86 Therefore, this hydrophilic HNTs-chitosan bionanocomposite could give a new appealing platform for additional studies on the redox behavior of proteins. The use of a direct electrochemistry approach is crucial for the development of innovative biosensors.…”

a Halloysite (HNT) is a promising natural nanosized tubular clay mineral that has many important uses in different industrial fields. It is naturally occurring, biocompatible, and available in thousands of tons at low cost. As a consequence of a hollow cavity, HNT is mainly used as nanocontainer for the controlled release of several chemicals. Chemical modification of both surfaces (inner lumen and outer surface) is a strategy to tune the nanotube's properties. Specifically, chemical modification of HNT surfaces generates a nanoarchitecture with targeted affinity through outer surface functionalization and drug transport ability from functionalization of the nanotube lumen. The primary focus of this review is the research of modified halloysite nanotubes and their applications in biological and medical fields.

“…There are various morphologies for HNTs, such as tubes, platy and spheres [1], and with 500 nm-1500 nm length, the lumen and external diameter respectively 15 nm and 50 nm [2]. HNTs possess a high surface area reached to 184.9 m 2 /g and large pore volume at 0.353 cm 3 /g [3] to form matrix membrane for gas separation [4]. HNTs chemical composition is similar to kaolin.…”

Halloysite nanotubes (HNTs) are natural occurring mineral clay nanotubes that have excellent application potential in different fields. However, HNTs are affected by size effect, surface electron effect and hydrogen bond formation on the surface which lead to weak affinity and prone to reunion at some extent. It is very significant to modify the HNTs' surface for expand its applications. In this review, the structural characteristics, performance and the related applications of surface modification HNTs are reviewed and summarized. we focus on the surface modified methods of HNTs, the effect of surface modification on materials and its related applications in various regions. In addition, future prospects and the meaning of surface modification have been discussed in HNTs studies. This review provided a reference for the application of HNTs modifications in new fields.

“…Chitosan is a natural organic polymer with excellent properties for an immobilization matrix for a biosensor such as low cost, high mechanical strength, good film-forming capability, biocompatibility and nontoxicity. [21][22][23] The modified Pt-Ru electrode showed sensitive CO detection in the physiological concentration range (0.9 to 9 μM), while it showed almost no current response to AA, UA and HP for the same concentrations to CO.…”
