To begin with, the manufacturing of HPMC nanotubes involves a multi-step process. The first step is the preparation of a HPMC solution, which is achieved by dissolving HPMC powder in a suitable solvent, such as water or organic solvents. The concentration of the HPMC solution plays a crucial role in determining the properties of the nanotubes, such as their size and stability.

Once the HPMC solution is prepared, it is then subjected to a templating process. This involves the use of a template, which can be a sacrificial material or a pre-formed structure, to guide the formation of the nanotubes. The HPMC solution is poured onto the template and allowed to dry or undergo a cross-linking reaction, depending on the desired properties of the nanotubes.

After the templating process, the template is removed, leaving behind the HPMC nanotubes. This can be achieved through various methods, such as dissolution, thermal decomposition, or physical removal. The choice of template removal method depends on the nature of the template material and the desired properties of the nanotubes.

Once the HPMC nanotubes are obtained, they undergo a series of characterization techniques to evaluate their physical and chemical properties. One of the most commonly used techniques is scanning electron microscopy (SEM), which provides high-resolution images of the nanotubes’ morphology and surface structure. SEM allows researchers to determine the size, shape, and uniformity of the nanotubes.

In addition to SEM, other techniques such as transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR) are also employed to characterize HPMC nanotubes. TEM provides detailed information about the internal structure of the nanotubes, while XRD and FTIR help identify the crystalline structure and chemical composition of the nanotubes, respectively.

Furthermore, the drug loading and release properties of HPMC nanotubes are also investigated.
