Bioimaging: Evolution, Significance, and Deficit

Abstract

Bioimaging is a digital technology-based medical advancement which is still relatively new. It has to do with real-time visualization of biological processes. This innovative imaging technology combines anatomical structure with functional data such as electric and magnetic fields, motion which is mechanical, and metabolism to provide information on anatomical structure. It's a non-invasive procedure that gives you a bird's-eye view of the human body, with more depth and detail as you go. As a result, bioimaging is a strong tool for seeing the interior functioning of the organism and its disorders. Examples of bioimaging in the medical industry include X-ray and ultrasound pictures, MRI, 3D and 4D body images utilizing Computed Tomography (CT) scans, DEXA scans which is useful for assessing bone density in osteoporosis, and so on. Maximum-resolution, two-positive charge fluorescent excitation microscopy, fluorescence redistribution after photobleaching, and fluorescence resonance energy transfer are some of the recent advancements in biological imaging. It provides us a cellular-level means of obtaining photographs of the entire body, anatomical locations, organs, tissues, and biological indicators. It may be used to aid illness management and therapy, as well as to detect, diagnose, and characterize the problems in clinical settings.

CARBON DOTS: Bioimaging and Anticancer Drug Delivery

“…Conventional techniques such as X-ray computed tomography (CT) are widely employed in the medical field, but they face limitations in rapidly providing detailed images of microstructures. [210] Numerous NPs have been explored for anticancer bioimaging due to their small size, which grants them strong permeability and retention -a phenomenon that allows NPs to accumulate in tumorigenic areas. [211] Various carbon nano allotropes similar in size and shape to CDs have been investigated for this purpose.…”

“…Depending on the target and techniques utilized, bioimaging can be categorized into molecular, biomedical, drug delivery, and computational bioimaging. Conventional techniques such as X‐ray computed tomography (CT) are widely employed in the medical field, but they face limitations in rapidly providing detailed images of microstructures [210] …”

A critical review on metal-organic frameworks (MOFs) based nanomaterials for biomedical applications: Designing, recent trends, challenges, and prospects

“…On this basis, Jain and research team [ 88 ] reported combining MOFs with various QD types can produce a hybrid with superior qualities compared to the separate components, exhibit stability including their excellent proportion of signal-to-noise, excellent sensitivity, profound penetration, and lack of tissue self-fluorescence interference and be employed for bioimaging and drug administration. Adding more, due to their functionalization, compositions, customized structure, and porosity, MOF-based nanocomposites have gained widespread recognition in positron emission tomography (PET), optical imaging (OI), computed tomography (CT), and magnetic resonance imaging (MRI) for intracellular imaging [ 153 ]. Magnetic resonance imaging (MRI) …”
