Nanomaterials for Biomedical Applications: Production, Characterisations, Recent Trends and Difficulties

Abstract

Designing of nanomaterials has now become a top-priority research goal with a view to developing specific applications in the biomedical fields. In fact, the recent trends in the literature show that there is a lack of in-depth reviews that specifically highlight the current knowledge based on the design and production of nanomaterials. Considerations of size, shape, surface charge and microstructures are important factors in this regard as they affect the performance of nanoparticles (NPs). These parameters are also found to be dependent on their synthesis methods. The characterisation techniques that have been used for the investigation of these nanomaterials are relatively different in their concepts, sample preparation methods and obtained results. Consequently, this review article aims to carry out an in-depth discussion on the recent trends on nanomaterials for biomedical engineering, with a particular emphasis on the choices of the nanomaterials, preparation methods/instruments and characterisations techniques used for designing of nanomaterials. Key applications of these nanomaterials, such as tissue regeneration, medication delivery and wound healing, are also discussed briefly. Covering this knowledge gap will result in a better understanding of the role of nanomaterial design and subsequent larger-scale applications in terms of both its potential and difficulties.

Rapid Magneto-Sonoporation of Adipose-Derived Cells

“…Biocompatible nanoscale materials have introduced outstanding innovation in biomedicine, finding use in the controlled delivery of biomolecules, manipulation of cell phenotype and behavior, and improvement of structural or biological features of substrates used for cell growth [50][51][52]. Key biological applications include non-invasive imaging and drug delivery in living organisms, as well as tissue engineering and wound healing [52][53][54][55][56][57][58].…”

Magnetite Nanoparticles: Synthesis and Applications in Optics and Nanophotonics

“…Nanotechnology is focused on the creation, investigation, and application of new types of materials, called “nanomaterials”, of which the size of at least one dimension is from 1 to 100 nm. Nanomaterials find their application in the broadest fields, including the chemical industry [ 1 , 2 , 3 ], agriculture [ 4 , 5 ], engineering [ 6 ], pharmaceutics [ 7 ], sustainable energy [ 8 ], medicine [ 9 , 10 , 11 ], etc.…”

Vitamin Supplementation Protects against Nanomaterial-Induced Oxidative Stress and Inflammation Damages: A Meta-Analysis of In Vitro and In Vivo Studies

“…With the rapid development of nanotechnology in the last decade, nanomaterials have been omnipresent in industrial products, medicines, food, and cosmetics due to their unique chemical and physical properties [ 1 , 2 , 3 ]. These extensive applications make nanomaterials unavoidably enter human bodies through respiratory inhalation, dermal penetration, oral ingestion, or injection routes, which subsequently results in toxic damages on various organs and tissues (e.g., lung, liver, kidney, spleen, heart, testis, et al) and contributes to the appearance of related diseases [ 4 , 5 ].…”
