Recent advancement of nanostructured materials: a compatible therapy of tissue engineering and drug delivery system

Research into drug delivery and tissue engineering (TE) has made great strides in the current era because of its limitless potential to enhance human health. In the meantime, the advancement of nanotechnology offers chances to categorize, control, and arrange orderly arrangements of materials at the nanoscale ranking. Biomaterials with the nanoscale organization have been applied to TE as artificial matrices and controlled-release drug reservoirs. Drug delivery systems may be created with precise control over composition, morphology, size, and shape. Their surface characteristics might be changed to improve solubility, immune compatibility, and cellular absorption. Current drug delivery methods include drawbacks such as poor bioavailability, ineffective targeting, and possible cytotoxicity. Dendrimers, nanoparticles, nanocapsules, nanotubes, and nano gels are auspicious and adaptable nano-scale medicine transportation methods. Small-molecule medications and numerous biomacromolecules can be delivered using them. Current TE scaffolds differ from earlier ones because they are based on something other than hydrolytically degradable macroporous materials. Methods highlight nanoscale topography resembling the natural extracellular matrix (ECM) to influence cell activities and tissue creation. Researchers were inspired to create nanofibrous congeners using electrospinning or self-assembly after realizing that the natural ECM is a multifunctional nanocomposite. It has been demonstrated that nanocrystal-containing nanocomposites stimulate active bone formation. TE and drug delivery are areas that are closely connected. The objective of TE is to achieve controlled distribution of mammalian cells, which can be seen as a specific example of medication delivery. Consequently, the effectiveness of TE will be improved by the controlled release of therapeutic elements. Both the medication delivery systems and the scaffolds used in TE must be biocompatible and biodegradable from a material standpoint. By creating biomaterials with regulated properties, the biotic capabilities of encapsulated pharmaceuticals and cells may be significantly improved. The latest advancements in using nanostructured ingredients for TE and medication delivery are summarised in this study.
