on working with nanomaterials in recent decades [1,2]. Because of their unique properties, nanomaterials are particularly well-suited for biomedical applications. They are facile to synthesize, can be modified in size, contain tunable surface chemistry, providelargesurface-to-volumeratios,andaregenerallybiocompatible[3]. All of these features make nanomaterials promising for almost all aspects of biotechnology, overcoming the many shortcomings in existing conven- tional materials [4]. Following a pioneering study by Higuchi et al. on albumin nanoparticles, it was suggested that nanomedicine could be an effective tool to target tumors and cancer cells as the ability to avoid im- mune system clearance is enhanced [5]. Nanoparticles have shown to have positive results against coronary artery disease, and cancer cells, by effec- tively avoiding clearance from immune system clearance [6e9]. Nano- particles can be used to deliver a large variety of pharmaceuticals in a way that is safer (through targeted nanomedicines by limiting the amount of drug delivered) and more effective [10]. Biological and medical nano- materials have been used for years, including liposomes [11], carbon nanoparticles [12e17], dendrimers [18], ceramic nanoparticles [19], iron oxide nanoparticles [20], titanium dioxide nanoparticles [21], magnetic nanoparticles, polymer nanocomposites [18], silica and metal nanoparticles [22]. Additionally, many different types of nanomaterials have been EmergingApplicationsofCarbonNanotubesinDrugandGeneDelivery ISBN978-0-323-85199-2 ©2023ElsevierLtd. https://doi.org/10.1016/B978-0-323-85199-2.00009-1 Allrightsreserved. 1 2 EmergingApplicationsofCarbonNanotubesinDrugandGeneDelivery proposed as means of drug/gene delivery that respond to external stimuli. In addition, drugs release from within these nanocarriers are triggered by changes in pH, redox potential, enzyme activation, thermal gradients, magnetic fields, light, and ultrasound [23]. Among the nanomaterials, carbon nanotubes (CNTs) have drawn tremendousinterestinthebiomedicalfieldbecauseofboththeirpromising properties, including high drug loading capacity [24], high stability [25], needle-like structure, high surface area [25], biocompatibility [26], flexible interaction with cargo, considerable strength, outstanding mechanical and electrical properties [27], and the ability to deliver drugs to specific tissues [28]. Despite the advantages, it also has some disadvantages related to toxicity and low biodegradability [29,30]. Although CNTs exhibit some undesirableproperties,theyarestillbeingutilizedinmedicineininnovative ways, such as in drug delivery systems, gene delivery, gene therapy, diag- nostic applications, as well as biosensors and vaccine delivery [29]. CNTs have a variety of appealing properties in biomedical applications, as shown in Table 1.1. Though CNTs have several desirable biological properties, their biosafetyisoftenanissueofconcern,particularlyinregardstotheiruseand theirbiomedicalapplications.Therefore,acomprehensiveassessmentofthe in vivo impact of CNTs is required before wide-scale commercial biomedical applications are undertaken. Studies on CNTs have been crit- icized for their inaccuracies and incompleteness, ranging from animal models that aren’t representative of human exposure routes to studies that lack even a thorough description of the impurities, chemistry, charge, and dimensionsofthestudiedCNTs[37].Graphenesheetsarerolledseamlessly as a cylindrical tube to form single-wall carbon nanotubes (SWCNT), as well as multi-walled carbon nanotubes (MWCNTs), which are composed of layers of graphene sheets stacked on one another. Moreover, there are three main methods for the manufacture of CNTs: chemical vapor depo- sition (CVD), laser ablation, and arc discharge [38]. In the current chapter book, we summarize promising and not-so-promising studies showing the importanceofCNTsinavarietyofbiomedicalapplications.Manyresearch studies,particularlyperformedinyear2016e2022,areassessedwithcritical insight into what these studies conclude. Herein, the uptake of CNTs, the delivery of pharmaceutical agents using CNTs has been covered. We also discuss concerns raised about the toxicology of CNTs at the end of this study and outline what and where the field urgently needs to grow.

Application Description References Diagnosing application Bioimaging Carbon nanotube’s optical, electronic and [31,32] and biosensing mechanical properties make it a promising material for the production of electrochemical and optical biosensors and some other applications deriving from CNTs because of their high photostability and lack of quenching Therapeuticalapplication Photothermal CNTs would produce heat by converting [33] therapy near-infrared radiation (NIR). Drug delivery The unique needle-like shape of carbon [34] nanotubes with the ability to quickly penetrate cell membranes makes them ideal carriers of drugs/genes due to their high surface area, multifunctional surface chemistry, lack of immunogenicity, and high surface area. Tissue Carbon nanotubes can be used in tissue [35] engineering engineering because of their biocompatibility, stiffness, mimicking of natural tissue nanofibers, cell adhesion and proliferation stimulation, and ability to form 3D structures. Lab-on-chip- Miniaturized systems such as lab-on-a-chip [36] devices devices are used to examine drugs, grow cells, and model diseases using tiny volumes of fluid flowing in various channels. The CNTs would be used in LOC devices as membrane channels, sensors, and channels walls. 1.2 Quantitative approaches Asignificantapplicationofnanoparticlesisthedeliveryofdrugs;becauseof theirlargesurfaceareas,nanoparticlesarecapableofdeliveringlargequantities ofdrugsorothermedicalcargos[39,40].Therefore,developingefficientdrug delivery systems is vital to human health [41]. Theranostic with nanotech- nology for cancer has emerged as a promising field that could integrate the 4 EmergingApplicationsofCarbonNanotubesinDrugandGeneDelivery treatment and diagnosis of cancer by combining nanotechnologies with therapeutic agents to enable targeted drug accumulation in cancer-specific cells without affecting normal cells [42].

From 1965 to 2021, bibliometric searches were conducted in Google Scholar, Scopus, PubMed, and Web of Science Core Collections (n¼70,300). Data were obtained from the online version of the core collection in Web of Science on January 15, 2022 [47]. The “Carbon nanotube*”OR“CNT*”OR“SWCNT*”OR“MWCNT*”toidentify allarticlesrelatedtotreatmentfrom1990to2022thatcontainthekeyword in the title list, and 189,358 publications were encountered. Also, articles using the keyword “Drug Delivery*” AND “Carbon nanotube*” OR “CNT*” OR “SWCNT*” OR “MWCNT*” to identify all articles from 1990 to 2022 that contain the keyword in the title which, 4748 publica- tions met the selection criteria. Upon further screening, only 3137 publi- cations were categorized through “Drug Delivery*” AND “Carbon Nanotube*” OR “CNT*” OR “MWCNT*” OR “SWCNT*” key- words that were utilized for further analysis. Moreover, more data for this study basedon title search were derivedfrom SCOPUS, and thetime span was from 1985 to 7rd February 7, 2022. Also, bibliometric studies were carried out on the Google Scholar and PubMed databases, resulting in 70,300 publications and 1353 publications. This data collection with an initialtitlesearch“DrugDelivery*”inthe“TitleofArticle”hasbeendone on another well-known database Scopus [47]. There were almost 38,996 documents with the title of “Drug Delivery*”; and nearly 125,277 docu- ments with the title of “Carbon Nanotube*” while the “CNT*” OR “MWCNT*” title search terms were used to retrieve the data.
