The development of functional materials and the use nanotechnology are ongoing projects. These fields closely linked, but there is a need to combine them more actively. Nanoarchitectonics, concept that comes after nanotechnology, ready do this. Among related research efforts, into creating through formation thin layers on surfaces, molecular membranes, multilayer structures these have lot implications. Layered especially important as key part nanoarchitectonics. diversity components used in layer-by-layer (LbL) assemblies notable feature. Examples LbL introduced this review article include quantum dots, nanoparticles, nanocrystals, nanowires, nanotubes, g-C3N4, graphene oxide, MXene, nanosheets, zeolites, nanoporous materials, sol–gel layered double hydroxides, metal–organic frameworks, covalent organic conducting polymers, dyes, DNAs, polysaccharides, nanocelluloses, peptides, proteins, lipid bilayers, photosystems, viruses, living cells, tissues. examples assembly show how useful versatile it is. Finally, will consider future challenges

Cancer significantly impacts human quality of life and expectancy, with an estimated 20 million new cases 10 cancer-related deaths worldwide every year. Standard treatments including chemotherapy, radiotherapy, surgical removal, for aggressive cancers, such as glioblastoma, are often ineffective in late stages. Glioblastoma, example, is known its poor prognosis post-diagnosis, a median survival time approximately 15 months. Novel therapies using local electric fields have shown anti-tumour effects glioblastoma by disrupting mitotic spindle assembly inhibiting cell growth. However, constant application poses risks like patient burns. Wireless stimulation via piezoelectric nanomaterials offers safer alternative, requiring ultrasound activation to induce therapeutic effects, altering voltage-gated ion channel conductance depolarising membrane potentials. This review highlights the mechanism, drug delivery, activation, current technologies cancer therapy, emphasising need further research address limitations biocompatibility whole systems. The goal underscore these areas inspire avenues overcome barriers developing nanoparticle-based therapies.

This study focuses on preparing piezoelectric polyvinylidene fluoride (PVDF) nanocomposites reinforced with silver nanoparticles (AgNPs) using an electrospinning process. The aim of this is to assess AgNPs' influence the properties PVDF and, therefore, create optimal composite enhanced properties, enabling its application in various fields both as sensor and actuator. Because electrical stimuli have proven a positive tissue engineering, combined AgNPs, which antimicrobial these composites demonstrate promising opportunity for biomedical scaffolds. proposed scaffolds were characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy Fourier transform infrared spectroscopy. In addition, mechanical are studied through tensile tests, while response measured in-house built setup coupling monitoring. An experimental test was numerical simulations COMSOL Multiphysics version 6.3 software package, paper also presents short review analytical methods used modelling simulation composites.
