Let's continue going over the basic knowledge that is required for developing whole dead human body 3D-scanner microscopy technology, so that we can advance human immortality biotech, neurotech, and artificial intelligence. Let's rock!

So, in general, as electromagnetic radiation wavelength becomes smaller, the biomatter penetration depth increases; however, the relationship is not completely linear, especially in the second near infrared range or around 1 μm light wavelength.

I will find out how exactly the varying light wavelengths affect biological cell nucleus, especially DNA. Light wavelength is inversely proportional to its energy, meaning as the light wavelength becomes smaller, its energy increases; lights with the smallest wavelengths such as gamma and x-rays can penerate deep into human body because they have more energy, and that high energy can damage DNA molecules.

I'll look more into DNA molecule binding force, and find out how much energy is required to damage and break up DNA strains.

One thing to note is that when microscopically 3D-scanning dead, not live, animal biomatter to find out its cell locations and tissue structures, using extremely harmful radiation such as ultraviolet rays, x-rays, and gamma rays is an option for their power to deeply penetrate biomatter; however, one required condition is that radiation must be reflected in biomatter and reach back microscope lens, so radiation with too much penetrative power that fails to meet that required condition cannot be used; however, when using harmful radiation for 3D-scanning biomicroscopy, the microscopy system must be completely enclosed in a safely shielded container, and the whole microscopy will have to be performed by a robot or a motorized instrument to keep away all the harmful radition from reaching a living human body. Later, I'll get into how, why, and when light reflects when it collides with biomatter.

Let's get back to infrared light.

Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon.

Infrared radiation is emitted or absorbed by molecules when changing rotational-vibrational movements. It excites vibrational modes in a molecule through a change in the dipole moment, making it a useful frequency range for study of these energy states for molecules of the proper symmetry. Infrared spectroscopy examines absorption and transmission of photons in the infrared range.

That is from Wikipedia entry on infrared light, and it suggests that infrared radiation is related to biomolecules, such as human biomolecules, in some way. I'll look into infrared biospectroscopy for biotech development research.

Dipole moment is the vector product of the charge on either pole of a dipole and the distance separating them.

Dipole, in physics, is any object (such as a magnet, polar molecule or antenna) that is oppositely charged at two points (or poles). Dipole, in chemistry, is any molecule or radical that has delocalised positive and negative charges.

Infrared radiation is used in industrial, scientific, military, commercial, and medical applications. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected.
