Cytotoxicity and effects on cell membrane integrity of the blank and TMZ-loaded dual-functionalized carbon nanostructures (CNs) were evaluated in vitro on a GBM cell line (U87MG), as well as their radiosensitizing properties after exposure of the pre-treated GBM cells to gamma radiation with a standard clinical dose for patients with GBM. All prepared formulations underwent biopharmaceutical and physicochemical characterization, including the formulations exposed to irradiation under the same conditions. For physicochemical characterization of the formulations, different techniques were used by which successful functionalization of the CNs and TMZ loading were confirmed and visualized; no significant changes in the structure of the CNs and TMZ after irradiation were observed. With single and dual functionalization, formulations with relatively high TMZ loading efficiency and drug content were prepared. They exhibited homogeneous particle size distributions and mean particle sizes and surface charges suitable for crossing the BBTB and targeting brain cancer cells. A biphasic drug release profile was observed for all functionalized TMZ-loaded formulations in simulated in vivo conditions, with a sustained release pointing to the potential for controlled release of TMZ in brain tumor cells. The formulations of the hybrid CN MWCNTs-G compared to the corresponding MWCNTs were characterized by a similar or slightly higher TMZ content, larger particle size, similar surface charge, and slightly faster TMZ release, which can be attributed to the planar structure of graphene that promotes TMZ binding to the surface on a larger scale. For the irradiated CNs, lower values for particle size, more positive values for surface charge, and accelerated TMZ release were observed, which could be explained by changes in the physicochemical characteristics of the prepared formulations upon irradiation.

Therefore, the selection of a suitable carrier material for rhizobacteria plays a crucial role in ensuring the sustained viability of these microorganisms. Nanomaterials, particularly nanohydroxyapatite (nHA), have garnered attention for sustaining rhizobacterial viability, high loading capacity, high biodegradability, and biocompatibility, which facilitate microbial interactions. In this study, nHA was synthesized using a hydrothermal method and used as a carrier for two rhizobacteria strains (Pd and Tb). The structural and morphological properties of nHA were examined through XRD and scanning electron microscopy analyses. Rhizobacteria were encapsulated within the carrier material, and their viability was evaluated using the total plate count method. Following their immobilization on nHA, the phosphate-solubilizing capacity of rhizobacteria was evaluated using Pikovskaya's medium. A nitrogen-free bromothymol medium was utilized to qualitatively assess the nitrogen-fixing ability of rhizobacteria. Furthermore, rhizobacteria were identified using 16S rRNA gene sequencing, followed by analysis to construct a phylogenetic tree. nHA was found to meet the required quality criteria, exhibiting a spherical morphology with an average particle size of 68 nm and a porosity of 54.78%. The nHA carrier demonstrated favorable physical attributes to sustaining rhizobacterial viability with pH 8.95 and an electrical conductivity of 55.4 μS/cm. Rhizobacteria loaded onto the nHA carrier maintained comparable viability to those without carriers. The highest viability of the rhizobacterial strains Pd and Tb loaded onto the nHA carrier was observed on the seventh day after inoculation, measuring at 2.480 × 10<sup>7</sup> and 1.040 × 10<sup>7</sup> CFU/mL, respectively. The qualitative tests of nHA as rhizobacterial carrier demonstrated that rhizobacteria retained their ability to solubilize phosphate and fix nitrogen.

Similarly, Tb rhizobacterium showed 100% similarity to <i>Bacillus altitudinis</i> strain NPB34b.
