Level 1 — Absolute Beginner
Scientists at Texas A&M University made a new tool. It uses a laser, a strong beam of light. The tool has a name, TRIP.
TRIP looks at tiny parts inside the body called proteins. Proteins are small pieces that do jobs inside living things. TRIP can see how proteins stick to each other and how medicine sticks to proteins.
The laser touches the proteins very gently. Then it reads small movements, like tiny shakes. These shakes tell scientists what is happening.
The scientists tested TRIP on a part of a virus. They found that TRIP can help show if a medicine will work well. This could help make new medicines for sickness like cancer.

Level 2 — Elementary
Researchers at Texas A&M University have invented a new laser based technique called TRIP, which stands for Thermostable Raman Interaction Profiling. It can measure forces that happen when proteins interact with each other, or when a drug binds to a protein, while everything sits in water like a real living cell.
TRIP works by using a laser to gently excite the tiny bonds inside protein molecules that are dissolved in a liquid. Then a method called Raman spectroscopy reads the vibrations, or small shakes, that come back. These vibrations tell scientists what kind of bonds are present.
For the first time, TRIP let scientists directly measure a weak but important type of bond called aromatic pi-pi stacking, sometimes nicknamed molecular velcro, inside a busy protein environment.
The team tested TRIP on the SARS-CoV-2 main protease, an important virus protein that the virus needs to copy itself. TRIP could predict how well antiviral drugs bind to this protein by tracking changes in the vibrations. Scientists believe TRIP could speed up drug discovery for cancer, Alzheimer's disease, and infectious diseases.

Level 3 — Intermediate
Researchers spanning the Institute for Quantum Science and Engineering and the departments of Chemistry, Biology, and Electrical and Computer Engineering at Texas A&M University have developed a new laser based technique called TRIP, short for Thermostable Raman Interaction Profiling. The method directly measures, for the first time, the quantum forces involved in protein interactions and drug binding under near physiological watery conditions.
TRIP works by using a laser to gently excite atomic bonds in a solution containing protein molecules. The resulting vibrations are then read through Raman spectroscopy, a method that identifies different types of bonds based on how they shake. This approach achieves the first direct, non-invasive quantification of aromatic pi-pi stacking interactions, weak but important bonds sometimes nicknamed molecular velcro, within complex protein environments.
To demonstrate the technique, the team applied TRIP to the SARS-CoV-2 main protease, an enzyme the virus needs in order to reproduce. By measuring changes in molecular vibrations, TRIP could predict how effectively antiviral drugs bind to the protease.
Researchers believe TRIP could accelerate drug discovery for diseases including cancer, Alzheimer's disease, and infectious diseases, since it gives scientists a direct way to study protein interactions that previously could not be observed directly. The findings were published in the journal Science Advances in late June 2026.

Level 4 — Advanced
A multidisciplinary team spanning the Institute for Quantum Science and Engineering and the departments of Chemistry, Biology, and Electrical and Computer Engineering at Texas A&M University has unveiled a laser based technique called TRIP, an acronym for Thermostable Raman Interaction Profiling, capable of directly measuring the quantum forces underlying protein interactions and drug binding under near physiological, aqueous conditions, a feat not previously achieved.
The method operates by using a laser to gently excite atomic bonds within a solution of protein molecules, then interrogating the resulting vibrational signatures via Raman spectroscopy to distinguish among bond types. In doing so, TRIP achieves the first direct, non-invasive quantification of aromatic pi-pi stacking interactions, weak yet functionally consequential bonds colloquially termed molecular velcro, as they occur within complex, crowded protein environments.
To validate the approach, the researchers applied TRIP to the SARS-CoV-2 main protease, the enzyme the virus requires to reproduce, demonstrating that shifts in molecular vibration could forecast the efficacy with which antiviral compounds bind to the target. The result offers a proof of concept for a broader class of diagnostic applications in structural biology.
Researchers anticipate that TRIP could accelerate drug discovery across a spectrum of conditions, including cancer, Alzheimer's disease, and infectious diseases, by furnishing investigators with a direct, empirical window onto protein interactions that had previously eluded observation. The findings appeared in the journal Science Advances in late June 2026.
