“…Kumar et al [ 94 ] synthesized Mn-doped ZnO nanoparticles utilizing the sol–gel approach through the addition of isopropyl alcohol to zinc acetate dihydrate, subsequent to the addition of manganese acetate and urea under constant stirring until the complete evaporation of the solvent, leading to the formation of a uniform gel. Then, the gel was subjected to calcination at 500 °C, while the obtained powder was further calcined at 600 °C for 2 h to receive crystalline Mn-ZnO nanoparticles.…”

The wide array of structures and characteristics found in ZnO-based nanostructures offers them a versatile range of uses. Over the past decade, significant attention has been drawn to the possible applications of these materials in the biomedical field, owing to their distinctive electronic, optical, catalytic, and antimicrobial attributes, alongside their exceptional biocompatibility and surface chemistry. With environmental degradation and an aging population contributing to escalating healthcare needs and costs, particularly in developing nations, there’s a growing demand for more effective and affordable biomedical devices with innovative functionalities. This review delves into particular essential facets of different synthetic approaches (chemical and green) that contribute to the production of effective multifunctional nano-ZnO particles for biomedical applications. Outlining the conjugation of ZnO nanoparticles highlights the enhancement of biomedical capacity while lowering toxicity. Additionally, recent progress in the study of ZnO-based nano-biomaterials tailored for biomedical purposes is explored, including biosensing, bioimaging, tissue regeneration, drug delivery, as well as vaccines and immunotherapy. The final section focuses on nano-ZnO particles’ toxicity mechanism with special emphasis to their neurotoxic potential, as well as the primary toxicity pathways, providing an overall review of the up-to-date development and future perspectives of nano-ZnO particles in the biomedicine field.

Among the many fluoropolymers, polyvinylidiene fluoride (PVDF) has been well-known since 1960s and is preferred for various electronic applications owing to its lower cost, inordinate mechanical properties, and tunable polymorphism. It is well known that PVDF exhibits five different crystalline polymorphs (α). Among all, β-crystalline phase is the most important with excellent piezoelectric, ferroelectric, and pyroelectric properties.Metal oxide nanoparticles (MO-NPs) are used in diverse applications, aided by their unique electrical, optical, magnetic, and catalytic properties. Many reports are available with a focus on the synthesis of Fe, Co, and Ni oxide magnetic NPs for data storage and sensor applications. More importantly, transition metal cations can exist in several different valence states and their crystallite size increased with increasing addition of metal doping. Incorporation of MO and doped MO with PVDF plays pivotal a role in improving the sensitivity of the piezoelectric sensor. This review covers the doping of PVDF with MO-NPs and their effectiveness towards in applications.

Some studies have been reported in the recent past on smart sensors for non-enzymatic glucose sensing applications. Nevertheless, little has been reported on the in-house development of low-cost 3D printed smart biomedical sensors with tunable sensitivity. This study reports investigations on the in-house, low-cost fabrication of polyvinyl difluoride (PVDF) matrix-based 3D printed tunable non-enzymatic glucose sensors. For fabrication of smart sensors, Cu (4%) doped ZnO nanoparticles have been reinforced (in different weight proportions (wt%) in PVDF matrix through melt processing. The results suggest that 4% reinforcement (of 4% Cu doped-ZnO), processed at 190°C, 40 rpm screw speed on twin screw extrusion (TSE) followed by post heat treatment (HT) at 60°C are the best settings for fabrication of feedstock filaments (for bio-sensor 3D printing). Finally, a PVDF-based sensor to support bioreceptor and transducer requirements has been successfully prepared (with 4D properties (i.e. one-way programing feature), optical, morphological, bond strength, piezoelectric and mechanical characteristics). The 3D printed electro-active sensor, (of selected composition) resulted in acceptable mechanical, piezoelectric, and dielectric properties (modulus of toughness (MoT) 1.46 MPa, Young’s modulus (YM) 1221.7 MPa, piezoelectric coefficient 19.3pC/N and dielectric constant 6.5). The results have been supported by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), current-voltage-resistance (I-V-R), and Fourier transformed infrared (FTIR) analysis.
