Flower like nanostructured ZnO hierarchical particles termed as NSPs exhibit high surface area as well as defect free growth which makes them competent for further exploration. In this work, a simple chemical approach to incorporate Chromium (Cr) as dopant in ZnO NSPs is utilized, ensuring the combined effect of effectual nature of pristine ZnO NSPs as well as visible light harvesting character owing to the Cr-doping. Using a simple wet-chemical approach, developed Cr-doped ZnO NSPs are developed having appreciable nanostructure characterized by scanning electron microscopy, energy dispersive spectroscopy, UV-vis spectroscopy, and other relevant techniques. As affirmed by the change in the color of ZnO NSPs as well as reduction in the bandgap value (E g ≈ 2.9 eV), ZnO NSPs exhibit significant increase in the photocatalytic degradation of Rhodamine B (RhB) dye that is taken as reference for determination of evolution of visible light dependent characteristics in ZnO NSPs. Nearly 70% degradation of RhB is obtained just in an hour which reflects the efficient photoactive behavior of Cr-doped ZnO NSPs.

Morphology effect is one of the essential factors that influence the performance of electrochemical biosensors based on ZnO nanostructures. These nanostructures are characterized by anisotropic growth with different dimensionalities such as zero-dimensional, one-dimensional, and two-dimensional. More interestingly, when combining each dimension into another advanced dimensionality, i.e. the three-dimensional (3-D), exceptional properties can be generated that are not otherwise found in low dimensionalities. The outstanding popularity of 3-D ZnO stems from many factors, with one of the most important being its synergic advantages from its low dimensional sub-unit and the additional surface area of the 3-D structure due to an increased geometric volume. This review briefly describes the principles and growth mechanism factors of 3-D ZnO via solution-based approaches and additional advanced methods. The paper further expands on the latest advancement of research into the 3-D ZnO nanostructure-based electrochemical biosensors to detect biomolecules that harm humankind. We also discussed the analytical performance of these biosensors using different nanocomposite materials. Additionally, limitations and suggestions on particular sensing works are proposed. Lastly, the five-year progress in research into 3-D ZnO-based electrochemical biosensors’ performance in healthcare diagnosis is compared and future challenges presented.
