“…Used graphene-based material can undergo similar disposal procedures to the currently utilized adsorbents in water treatment plants, which tend to forgo regeneration procedures in the United States. While the biocompatibility of graphene and graphene-based nanomaterials in terms of their antibacterial properties, [72][73][74][75][76][77][78][79] antifungal properties, 80,81 and cytotoxicity on human cells [82][83][84][85][86] has been demonstrated for biomedical and environmental applications, only a few human cell lines have been studied. Hence, additional research is necessary before determining the health and environmental impacts of graphene.…”

Increasing human activity, including commercial and noncommercial use of pharmaceuticals, personal care products, and agricultural products, has introduced new contaminants that can be challenging to remove with currently available technologies. Pharmaceuticals, in particular, can be especially challenging to remove from the water supply and can pose great harm to people and local ecosystems. Their highly stable nature makes their degradation with conventional water treatment techniques difficult, and studies have shown that even advanced treatment of water is unable to remove some compounds. As such, decontamination of water from pharmaceuticals requires the development of advanced technologies capable of being used in indirect and direct potable water reuse. In this review, we discuss pharmaceutical removal in indirect potable water treatment and how recent advancements in adsorption and photocatalysis technologies can be used for the decontamination of pharmaceutical-based emerging contaminants. For instance, new materials that incorporate graphene-based nanomaterials have been developed and shown to have increased adsorptive capabilities toward pharmaceuticals when compared with unmodified graphene. In addition, adsorbents have been incorporated in membrane technologies, and photocatalysts have been combined with magnetic material and coated on optical fibers improving their usability in water treatment. Advancements in photocatalytic material research have enabled the development of highly effective materials capable of degradation of a variety of pharmaceutical compounds and the development of visible-light photocatalysts. To understand how adsorbents and photocatalysts can be utilized in water treatment, we address the benefits and limitations associated with these technologies and their potential applicability in indirect potable water reuse plants.

“…13 Accordingly, GO sheets could also act as biocompatible sites for adsorption of bacteria but the bacterially-reduced GO sheets potently inhibit bacteria proliferation on their surfaces. 14 Up to now, the antimicrobial properties of GO have been successfully used to stainless steel, 5 cotton fabric, 15 polymer lms, [16][17][18][19][20] and water treatment membranes. 6,[21][22][23][24][25][26][27] However, whether GO can modulate microbial community in vivo still remains unknown.…”

“…The latter include nanostructures, such as carbon nanotubes (CNTs) [ 195 ], graphene [ 207 ], graphene oxide (GO) [ 208 ], reduced graphene oxide (RGO) [ 209 ] and others, and are well-known for their applications in biomedical engineering [ 210 ] and other biological applications [ 211 ], including drug delivery [ 212 , 213 ], sequential enrichment of peptides [ 214 ], osteoporotic bone regeneration [ 215 ], enzyme immobilization [ 216 ], biomaterials and bionics [ 217 ], generation of neurons [ 218 ], cellular migration [ 219 ], etc. Most of these nanomaterials can be routinely produced [ 220 , 221 ] or synthesized [ 222 , 223 , 224 ], even in common organic solvents used to also dissolve polymers [ 209 ] and possess important antimicrobial properties [ 225 , 226 , 227 , 228 , 229 , 230 ]. Such materials kill microbes through their physical interaction with the microbial surface leading to localized degradation of microbial cell walls [ 231 ] through wrapping, insertion or nano-knife-like processes [ 232 ].…”

Pathogenic microbes are the main cause of various undesired infections in living organisms, including humans. Most of these infections are favored in hospital environments where humans are being treated with antibiotics and where some microbes succeed in developing resistance to such drugs. As a consequence, our society is currently researching for alternative, yet more efficient antimicrobial solutions. Certain natural and synthetic polymers are versatile materials that have already proved themselves to be highly suitable for the development of the next-generation of antimicrobial systems that can efficiently prevent and kill microbes in various environments. Here, we discuss the latest developments of polymeric structures, exhibiting (reinforced) antimicrobial attributes that can be assembled on surfaces and coatings either from synthetic polymers displaying antiadhesive and/or antimicrobial properties or from blends and nanocomposites based on such polymers.
