“…SNP was nanosized (~50–100 nm) and roughly spherical, whereas ES was mostly non‐uniform and in the micron range. Previously, the shape and size have been reported to be spherical and ~20 nm, respectively 12 . The EDX analysis results showed the presence of sulfur was in both SNP and ES.…”

“…SNPs were prepared by following the method of Saedi et al (2020) using ES and sodium sulfide 12 . For this, 20 ml of 1‐M sodium sulfide was heated up to 100°C, added 1.6 g of ES and stirred vigorously for 1 h. The yellow colour of ES turned red, indicating the formation of polysulfide.…”

“…Several reports have already confirmed that adding antimicrobial nanoparticles improves the physical and functional properties of packaging films 1,7,9 . As one of the new functional nanomaterials, sulfur nanoparticles (SNPs) have emerged to prepare functional packaging films 11–13 . The antibacterial properties of elemental sulfur (ES) have long been recognized, and various forms of sulfur have been used effectively in dermatological treatment 14 .…”

“…The biological activity of ES has been known for a long time, but its practical use has been limited because of its hydrophobicity. Sulfur powder is hydrophobic and difficult to dissolve or disperse in most solvents 12,13 . Therefore, the preparation of SNPs was considered a convenient solution to expand the application of sulfur 14,15 .…”

“…Because commonly used Ag, ZnO and TiO 2 nanoparticles have strong antibacterial activity against either Gram‐positive or Gram‐negative bacteria, SNPs having strong antimicrobial properties against both Gram‐positive and Gram‐negative bacteria are advantageous for producing antimicrobial films 1,7,9 . Extensive studies have been conducted on the efficacy of SNPs as antibacterial agents 12,16,17 to prepare antibacterial functional films using various biopolymers like alginate, chitosan and pectin 11,13,18 . However, SNPs have never been used to manufacture LDPE‐based antibacterial packaging films using a melt‐ extrusion method.…”

Preparation of low‐density polyethylene‐ and poly (lactide)/poly (butylene adipate‐co‐terephthalate)‐based antibacterial films integrated with elemental sulfur and sulfur nanoparticles

Antibacterial low‐density polyethylene (LDPE)‐ and poly (lactide)/poly (butylene adipate‐co‐terephthalate) (PLA/PBAT)‐based films incorporated with elemental sulfur (ES) and sulfur nanoparticles (SNPs) were prepared using a blow extrusion method for food packaging applications. Flexible and free‐standing films were manufactured using an industrial processing method without any modification. The films were characterized using ultraviolet (UV)–visible spectroscopy, field emission scanning electron microscope (FESEM), X‐ray diffraction (XRD), Fourier transform infrared (FTIR) and thermogravimetric analysis (TGA). Also, film properties include optical, mechanical, surface hydrophobicity, thermal stability and antibacterial activity. The addition of ES and SNP significantly reduced the light transmittance (both UV and visible light) of LDPE‐ and PLA/PBAT‐based films and slightly reduced mechanical properties but did not affect thermal stability. The ES‐ and SNP‐added films showed apparent antibacterial activity against the Gram‐positive foodborne pathogenic bacteria (Listeria monocytogenes). In general, SNP showed superior film properties and antibacterial properties compared to ES, but ES also showed comparable properties as SNP. Antibacterial LDPE‐ and PLA/PBAT‐based films can be produced on an industrial scale and used in the packaging of refrigerated foods susceptible to L. monocytogenes contamination.

Sulfur nanoparticles (SNPs) have shown good potential in numerous fields due to their unique composition and properties. However, the direct utilization of abundant and inexpensive elemental sulfur for the large‐scale fabrication of high‐quality SNPs is still in its infancy. Herein, a simple one‐pot approach for the preparation of SNPs is presented, and gram‐scale SNPs can be readily prepared in one batch in the laboratory. By adding elemental sulfur‐ethylenediamine precursor to the acidic chitosan (CS) solution, chitosan‐capped sulfur nanoparticles (CS‐SNPs) can be formed immediately. Benefiting from the capping of CS, CS‐SNPs simultaneously possess small and uniform size with an average diameter of 19 nm, good aqueous dispersibility and stability, and favorable antioxidant capability against 2,2′‐azino‐bis (3‐ethylbenzothiazoline‐6‐sulfonic acid) free radicals. Moreover, CS‐SNPs also exhibit fine antibacterial activity against Staphylococcus aureus, and the minimum and optimal inhibitory concentrations are 256 and 512 µg mL−1, respectively. Considering the easy fabrication process and attractive attributes of CS‐SNPs, this investigation not only offers an effective method for the scalable fabrication of robust SNPs but also provides a feasible way for the value‐added utilization of elemental sulfur.

Low‐dimensional sulfur nanomaterials featuring with 0D sulfur nanoparticles (SNPs), sulfur nanodots (SNDs) and sulfur quantum dots (SQDs), 1D sulfur nanorods (SNRs), and 2D sulfur nanosheets (SNSs) have emerged as an environmentally friendly, biocompatible class of metal‐free nanomaterials, sparking extensive interest in a wide range application. In this review, various synthetic methods, precise characterization, creative formation mechanism, delicate functionalization, and versatile applications of low dimensional sulfur nanomaterials over the last decades are systematically summarized. Initially, it is striven to summarize the progress of low dimensional sulfur nanomaterials from versatile precursors by using different synthetic approaches and various characterization. Then, a multi‐faceted proposed formation mechanism with emphasis on how these different precursors produce corresponding SNPs, SNDs, SQDs, SNRs, and SNSs is highlighted. Besides, it is essential to fine‐tune the surface functional groups of low dimensional sulfur nanomaterials to form new complex nanomaterials. Finally, these sulfur nanomaterials are being investigated in bio‐sensing, bio‐imaging, lithium–sulfur batteries, antibacterial activities, plant growth along with future perspective and challenges in emerging fields. The purpose of this review is to tailor low dimensional nanomaterials through accurately selecting precursors or synthetic approach and provide a foundation for the formation of versatile sulfur nanostructure.
