“…It can be used for photodynamic therapy (PDT) and photothermal therapy (PTT) under single light source excitation. Modification of Te nanomaterials improves their biocompatibility, reduces toxicity, and confirms their therapeutic efficacy in biomedical applications [41]. Similarly, CdTe nanocrystals were obtained when E. coli cells were added to Na 2 TeO 3 and CdCl 2 in a reducing environment.…”

Using seleno-compounds and telluric compounds is a practical approach for developing solutions against drug-resistant bacterial infections and malignancies. It will accelerate the search for novel treatments or adjuvants for existing therapies. Selenium and tellurium nanospheres can be produced by lactic acid bacteria. The bacteria can differentiate the selenium and tellurium when the medium contains both selenite and tellurite. Therefore, our question in this study was the following: are they making alloys from the selenium and tellurium and what will be the composition, color, and shape of the nanoparticles? We used a simple microbial synthesis to produce nanoselenium, nanotellurium, and their alloys from sodium selenite and sodium tellurite using Lactobacillus casei. This bacterium produced red spherical amorphous elemental selenium nanospheres with a diameter of 206 ± 33 nm from selenite and amorphous black nanorods with a length of 176 ± 32 nm and a cross-section of 62 ± 13 nm from tellurite. If the initial medium contains a mixture of selenite and tellurite, the resulting nanoparticles will contain selenium and tellurium in the same ratios in the alloy as in the medium. This proves that Lactobacillus casei cannot distinguish between selenite and tellurite. The shape of the nanoparticles varies from spherical to rod-shaped, depending on the ratio of selenium and tellurium. The color of nanomaterials ranges from red to black, depending on the percentage of selenium and tellurium. These nanomaterials could be good candidates in the pharmaceutical industry due to their antipathogenic and anticarcinogenic properties.

The development of a multi‐functional solar‐driven interfacial evaporation (SDIE) system remains a significant challenge for its large‐scale applications. By taking advantage of high surface area, excellent young's moduli, anchoring/coupling capability, large absorption surface, strong absorption in the broadband solar spectrum, and efficient photothermal conversion efficiencies of 2D emerging materials (Xenes, Mxenes, etc.), hybrid SDIEs are developed to increase the use of solar energy beyond water production. This work aims to offer a systematic review of the recent advancement in 2D emerging materials except for graphene and their significant role in hybrid SDIEs to stimulate both fundamental and applied research on utilizing the underutilized auxiliary energy sources for future integrated water, energy, and environmental systems. For this purpose, first, the most recent progress in 2D photothermal materials is discussed, mainly including emerging Xenes, MXenes, and TMDs‐inspired hybrid SDIEs. Second, structural optimization strategies and modulation of the intrinsic photothermal performances of 2D emerging materials are highlighted. Third, the cutting‐edge conceptual designs developed in many hybrid applications such as thermoelectricity, salt recovery, and hydrogen production are broadly presented. Lastly, the current challenges and perspectives of 2D emerging materials and their hybrid evaporation structures are also mentioned.
