QDs are geometrical structures of semiconductor crystals.
A subclass of QDs are the optically active quantum dots (OAQDs), representing only those QDs that can interact with light quanta (photons).

PHYSICS
a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents.
an analogous discrete amount of any other physical quantity, such as momentum or electric charge.
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.[2]: 1.1 It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.
Bond dipole: The partial charges assigned to bonded atoms due to differences in electron density caused by electronegativity, inductive effects, and other factors. Indicated with δ+ and δ- and/or the arrow symbol.
Solid lipid–polymer hybrid nanoparticles (SLPN) are nanocarriers made from a combination of polymers and lipids, integrating the advantages of biocompatible lipid-based nanoparticles and gastrointestinal (GI)-stable polymeric nanoparticles.
Dissociation is a way the mind copes with too much stress.
Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species (ROS) and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage. Disturbances in the normal redox state of cells can cause toxic effects through the production of peroxides and free radicals that damage all components of the cell, including proteins, lipids, and DNA. Oxidative stress from oxidative metabolism causes base damage, as well as strand breaks in DNA. Base damage is mostly indirect and caused by the ROS generated, e.g., O2− (superoxide radical), OH (hydroxyl radical) and H2O2 (hydrogen peroxide).[1] Further, some reactive oxidative species act as cellular messengers in redox signaling. Thus, oxidative stress can cause disruptions in normal mechanisms of cellular signaling.
Multiple personality disorder is the former name for what is now known as dissociative identity disorder (DID). It is characterized by a disruption in memory, self-awareness, identity, or perception.
