Ethical medical research/Alternatives to animal testing
Non-animal testing techniques for medical purposes are efficient and far advanced. Alternatives to animal testing make use of medical imaging, microdosing, metabolism simulation, biochips, mathematics, visualizations and other methods. These advanced techniques give great insight, otherwise not offered by use of animal testing. The human mind is capable of solving problems related to medicine. If humans are able to determine the chemical composition of distant galaxies, imagine the potential for non-invasive technology to model tissue interactions.
This type of research is also cost effective, while improving speed and quality towards research.
The way and redundancy in which animal testing is carried undermines the capability for human innovation. Animal testing also desensitizes participants, and it influences the idea of the lack of value for life, which further reduces the quality of this type of research. Research from animal experimentation is limited, since animals do not have "all the same maladies as do humans."
Included in this resource is personal research, which is medical training.
Medical imaging 
Medical imaging can give great details of the inner workings of the human body. This method is far more efficient than animal dissections for determining effects on living tissue. Dyes that can cross the brain-blood barrier can be used to improve medical imaging for human observations, and dyes can be used for in vitro observations as well.
Microdosing uses medical imaging to see how the body metabolizes miniscule drug amounts. This is an example of an in situ human observation. In situ is taking observations without harm to an organism while it is alive.
Hyperspectral imaging 
Hyperspectral imaging is being developed and standardized for use in advanced biological sensing. It appears to have unprecedented detail of living tissue, displayed on a hyperspectral image projector. Hyperspectral imaging already has uses in astronomy, mineralogy, physics, agriculture, surveillance, environment, chemistry and other sciences.
Nanosensor imaging 
Nanosensors are able to detect cellular activity, with the aid of dyes. Cultured cells are grown in a laboratory, then nontoxic dyes display to nanosensors the metabolic activity of the cells. When a chemical is toxic to the cell, the metabolic activity of the cell reduces or halts, sometimes as the cell dies.
- External multimedia: Organ on a chip
Organ on a chip is a biochip layered with organ-specific tissue. Medication safety and interactions can be tested on it. Using biochips are less costly and less time extensive than animal testing. Another added benefit of using biochips, is that less training is required for use of this approach. Biochips are an example of in vitro laboratory testing.
There is a new technology that allows for cells to be suspended in air. A nontoxic magnetic filament is placed inside the cells to allow them to levitate, and this is useful for improving toxicity testing on cells.
Another recently developed technology uses a different type of biochip to separate microscopic organisms or cells based on size. Centrifugal force is generated by lasers to separate particles by size. This has uses for: "medical diagnostics; testing food, water and contaminated soil; isolating DNA for gene sequencing; crime-scene forensics; and pharmaceutical manufacturing."
Biosensors and electronics 
Information can be relayed to a microchip from magnetic sensing that detects biological reactions. Thousands of sensors can be placed on a small area to detect microscopic reactions. Uses include drug testing, protein interactions, and cancer detection. It is capable of sensing on a smaller scale than was possible before.
Applied mathematics 
In papyro is an experiment done on paper, which in this case is by math.
Math can be used to find out which peptides, by attachment, will be effective against viruses. Math use reduces the vast amount of peptides that would have to be tested. From here, the peptides could be further engineered. This is speculated for use with other types of microorganisms.
Mutation patterns by bacteria can be documented, then formulated. Future mutations can be calculated using these formulas. Other disease patterns, for instance leukemia activity, can also be charted, for timing of medication treatments.
Computer simulation 
The brain of a mouse has been simulated on a computer at a reduced speed and scale, and there is future potential for this technique. Simulating viruses and their interactions with other organisms has been done before. This is considering the simplicity of viruses, compared to complex organisms, makes them easier to simulate. Protein interactions of larger organisms can also be practically simulated.
Helmet design based on head injury susceptibility, physics and function can be improved using computer simulation. Simulations can be done comparing injuries without helmets to helmets and their modifications.
Mannequin simulation 
The use of test mannequins can help students practice crucial skills before performing medical procedures on real patients. Mannequins that simulate real conditions are highly effective and efficient at teaching, and they are a standard at medical schools.
Sample analysis 
Sample analysis can be of urine, swiping, fine-needle aspiration, blood or other sample. Spectrochemical analysis is one way of determining the metabolites or other chemical medium through light frequency analysis. Direct analysis can also be made of, chemical reaction, pH, specific gravity, or other measure.
