Drug Delivery Based on 2D Materials
One of the finest ways for performing targeted medicine administration and reducing patient side effects is to use drug delivery systems. Two-dimensional (2D) materials have the highest specific surface area of all known materials since they are the thinnest, and they can be employed as vast reservoirs and anchor points for the efficient loading and distribution of medicines. Furthermore, by integrating their superior physicochemical, optical, and electrical features with cell imaging, chemotherapeutic, photothermal (PPT), and photodynamic (PDT) therapies, they can be used to construct smart drug delivery systems.

Our Materials Research
Surface characteristics of 2D materials play an essential role in successful drug delivery in drug delivery applications.
Graphene Materials (GMs)
GMs are the first 2D materials that we have explored as carriers for drug delivery systems by exploiting their surface properties.
In combination with PPT and PDT, the TMD material MoS2 shows a lot of promise in drug delivery systems. This is owing to the fact that monolayer MoS2 has a 7.8 times higher NIR absorbance than GO. Furthermore, because MoS2 features unsaturated d orbitals, chemically active edge defects, and sulfur vacancies that can serve as sites for the introduction of functional groups and ligands, its surface chemistry is rich in functionalization properties.
However, MoS2 exhibits low serum stability and inefficient intracellular delivery. Alfa Chemistry can functionalize the surface of MoS2 with biocompatible materials and/or biomolecules to alleviate these difficulties, improve biocompatibility, and further minimize cytotoxicity.
h-BN is another ideal 2D material that has piqued our curiosity. Surface chemical inertness, multilayer surface porosity, high specific surface area, low toxicity, and high thermal conductivity are only a few of its advantages.

2D Material Solutions
Alfa Chemistry can provide or customize a variety of 2D materials for antimicrobial and antifouling surface applications. Besides GMs, MoS2, and h-BN, many other 2D materials have been used for this purpose based on the combination of drug delivery and PPT-PDT processes, mainly with strong light absorption in the near-infrared region.
