“…CNs can be prepared by different methods but chemical-vapour deposition (CVD) is used most commonly. This process involves the reaction of a metal catalyst with a hydrocarbon feedstock at high temperatures (>7008C) [41]. The common use of Ni as catalyst has raised serious concern about their subsequent use in biomedical applications.…”

“…This response is a result of biological, chemical, mechanical or electrical reactions occurring on the sensor. Examples of nanobiosensors are quantum dots, fluorescent nanoparticles, metallic nanoparticles, CNs [41], pH sensors or oxygen sensors that use nanotechnology for locally discrete measurements or a molecule-release sensor (such as release of calcium or potassium) [46]. Energy supply of nanosensors can be provided through the integration of motor proteins that function through ATP [47].…”

“…MWNT functionalisation is thus required and involves the addition of functional groups such as carboxyl or alcohol groups to the walls and ends of the nanotubes. This should prevent MWNT aggregation and allow for their incorporation into polymer sca olds [30] (Figure 1). Then, the P3HB/MWNTs solution was loaded in the syringe, and the syringe was placed in its special container.…”

“…This should prevent MWNT aggregation and allow for their incorporation into polymer sca olds. Once again, their large surface area makes MWNTs useful for tissue engineering purposes as large amounts of biomolecules can be placed onto the nanotubes [30][31]. Jang et al manufactured nanocomposite sca olds made of polylactic glycolic acid and MWNTs using the electrospinning technique [32].…”

Abstract. The aim of this study is to evaluate the e ects of Multi-Walled Carbon NanoTubes (MWNTs) on the structural and mechanical properties of poly-3-hydroxybutyrate (P3HB) electrospun sca olds. To achieve optimal properties of the electrospinning machine, P3HB polymer solutions were prepared at di erent concentrations and spinned in di erent electrospinning parameters. After optimization, MWNTs in di erent weight percentages (0.5%, 0.75%, 1%, and 1.25%) were added to the polymer solutions and electrospinned. The e ects of MWNTs on the structure of bers were investigated using Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Fourier transform infrared spectroscopy (FTIR) techniques. The addition of MWNTs increased the average ber diameter from 210 (neat P3HB) to 700 nm at 1.25% MWNTs. In addition, SEM photomicrographs and the MATLAB software program showed an increase in porosity from 81% to 84% in the presence of MWNTs. Tensile strength of P3HB/MWNTs composites revealed 158% improvement over pure P3HB sca old. According to mechanical and structural properties, the best amount of MWNTs was 0.5 wt%. Therefore, MWNTs with low percentages can signi cantly improve the mechanical properties of pure P3HB sca old, so that they can become favorable mechanically for tissue engineering applications.

Nanomaterials are anticipated to revolutionize disease detection and treatment leading to the realization of a potential world market of medical nanotechnology estimated to be > $3 billion within the next 5 years. This article provides an up to date summary of the current research investigations on Nanomaterials for medical applications. Nanomaterials have been categorized based on their shape, and within each shape they have been further categorized based on their chemical composition. Similarly, the medical applications have been categorized into four main sections:medical diagnosis, medical treatment, medical devices, and tissue engineering. Prior to the discussion of medical applications, approaches to biofunctionalization of nanomaterials are also presented as it is very important that the nanomaterials are compatible in biological environment for their application in medicine.
