Imagine you need to measure a speck of dust that is a thousand times thinner than a human hair. Moreover, the speck does not stay still but moves chaotically in a liquid. This is exactly the task that pharmacists face every day when controlling the quality of modern medicines. And now – for the first time in Russia – they will have a single, legally approved recipe for such a measurement.

The Ministry of Health of Russia has approved the draft general pharmacopoeia monograph developed by the team of the Department of Pharmaceutical and Toxicological Chemistry of RUDN Institute of Medicine. The document establishes a state quality control standard for a whole class of drugs — colloidal solutions, emulsions, nanoparticles, and even vaccines.

The team: who created the quality standard

• Anton Vladimirovich Syroeshkin – Doctor of Biological Sciences, Professor, Head of the Department.
• Tatyana Vadimovna Pleteneva – Doctor of Chemical Sciences, Professor.
• Olga Valerievna Levitskaya – PhD in Chemical Sciences, Associate Professor.
• Elena Valerievna Uspenskaya – Doctor of Pharmaceutical Sciences, Professor.

What is a “colloid” and why can’t it be seen?

When we buy drops, a spray, or an injection solution at the pharmacy, we think the liquid in the ampoule is absolutely transparent and homogeneous. But that is not really true. Many modern medicines are colloidal systems. In simple words, tiny solid particles or oil droplets float in the liquid — so small that the eye cannot see them.

Examples from everyday life:

• protargol (nose drops) is a colloidal silver solution;
• polyglucin and hemodez, which save lives in blood loss are also colloids;
• even some next‑generation vaccines are based on virus‑like particles smaller than 150 nanometres.

The problem is that particles up to 400 nanometres are invisible to optical microscopes — they are smaller than the wavelength of light. Controlling their quality is like checking the evenness of a seam while wearing very thick mittens.

Laser magic: how to “catch” the invisible?

The method standardized by RUDN scientists is called Dynamic Light Scattering (DLS).

A colloidal solution is illuminated with a laser, and a special sensor detects how the intensity of the scattered light changes over time. The particles in the liquid are in constant thermal motion. Large particles “tremble” slowly, small ones quickly. By analysing this “trembling”, a computer calculates the exact size.

The particle size in a drug is a safety and efficacy factor. “Particles that are too large can clog capillaries or not be absorbed. Non‑uniform size means the dose of the active substance will ‘wander’ from ampoule to ampoule. And in vaccines based on virus‑like particles, size critically affects how the immune system ‘sees’ the enemy,” says Elena Uspenskaya.

RUDN sets the standard

The DLS principle itself has been used in science and industry since the 1990s. However, it was only included in the list of mandatory drug control methods of the European Union in 2023–2024. Russia is not copying Western regulations but is developing its own, deeper and more precise.

The European version describes the method quite generally. The RUDN version contains an extensive block of theory and mathematical models, eliminating any ambiguity. It specifies requirements for sample preparation —how to filter the solvent and at what temperature to measure. Moreover, the monograph is tailored to the national regulatory framework and uses terminology familiar to Russian pharmacists.

“The development of a general pharmacopoeia monograph turns the DLS method from a suitable analytical tool into a mandatory element of regulated control. The monograph introduces universal criteria: what polydispersity index is considered acceptable, what Z‑average value should be recorded in the drug passport. This will reduce variability of methods and related errors in particle size determination for medical solutions. It will also facilitate comparability of results both at the stage of drug registration and when publishing scientific results – through a unified terminology, test parameters, and experimental quality criteria,” says Elena Uspenskaya.

Regarding the impact on the educational process, after the monograph is approved, changes may be made to the content of the discipline “Physical and Colloidal Chemistry”. At the same time, as Elena Valerievna notes, the content of the disciplines “Methods of Pharmacopoeial Analysis” and “Drug Quality Control” at the RUDN Institute of Medicine already includes blocks on dynamic light scattering.

Currently, the draft general pharmacopoeia monograph is undergoing scientific and technical editing at the Institute of Pharmacopoeia and Standardization. It is expected that already in the first quarter of 2026, an order of the Ministry of Health will approve this monograph as part of the State Pharmacopoeia of the Russian Federation.

In honor of the 66th anniversary of our university, 95 diplomats from 60 countries gathered in its walls. At the round table “All flags at RUDN”, the university presented a new educational course and talked about other programs and study opportunities at the university for foreign citizens.

Promotion of the Russian language

Oleg Yastrebov, Rector of RUDN, made a short presentation for the guests. He noted that the university has seen a significant increase in interest in learning the Russian language. For the past two years, the number of foreigners enrolled in philological fields has increased by almost 80%.

The Digital Preparatory Faculty significantly helps in promoting the Russian language abroad. About 7,000 people from 85 countries are currently studying there. On the online platform, they not only learn the language, but also gain the knowledge necessary for admission in the fields they are interested in: humanities, natural sciences, engineering, biomedical, and economics.

Since 2025, the RUDN Generation program has been successfully operating on the platform of the Digital Preparatory Faculty, and more than 200 people are already participating in it. Foreign university graduates and their family members study Russian online for free.

In the same year, RUDN launches a special Russian language training program for diplomats.

“We offer free Russian language training to employees of diplomatic missions of foreign states located in the territory of the Russian Federation. We have developed an individual program for ambassadors” said Oleg Yastrebov, Rector of RUDN.

The training will take place on the Digital Faculty platform. The course duration will be 4 months.

Education on request

In his report to the participants of the round table, the Rector also highlighted a special priority of RUDN — designing educational programs for specific needs of economies.

“We are initiating the creation of educational programs in such fields as engineering, agricultural technology, medicine and ecology,” said Oleg Yastrebov.

A striking example is the Sustainable Urban Development program, developed at the request of the Ghanaian authorities. At the end of 2025, 45 municipal managers of the country passed it. Ghanaian specialists not only attended lectures by RUDN experts and thematic seminars but also participated in practical exercises analyzing real-world cases from their professional field. The program also included workshops and excursions to urban infrastructure facilities, such as the EcoLine company, which deals with waste removal, sorting, recycling and disposal.

Another important project is the English-language master’s degree program “Agroholdings for the Global South”. It trains agronomists for countries in Asia, Africa and Latin America, considering local specifics.

Support for international students

Mikhail Katsarsky, Vice-Rector for Student Affairs, told the guests in detail about the support system for foreign students. He noted that 94 active national communities, where compatriots help newcomers, play an important role in the adaptation of students.

In addition, according to the Vice-Rector, when settling into a dormitory, an international principle applies — there is a Russian student in every room with a foreigner to promote language practice.

Mikhail Ilyich paid special attention to the support of student families. The university has two children’s rooms, one of them opened together with the family floor in the 1st building of the dormitory. About 30 families living on campus are international students.

“Students and university staff can leave their children in the rooms for several hours under the supervision of professional educators,” said Mikhail Katsarsky.

The Vice-Rector also told the guests about the university’s One-Stop Center, which provides over 90 services, and about the Interclub studios, where students can discover their creative talents.

The way to free learning through competition

Marina Reketz, Vice-Rector for International Affairs, reminded the diplomats about the key admission tool for foreigners — the RUDN Open Olympiad.

Its winners get the opportunity to enrol in our university under the quota of the Russian Government. The winners get a substantial discount on tuition. The participants of the Olympiad are tested face-to-face or online in their chosen field (physics, chemistry, computer science, ecology, and others), after which the online participants will have a video interview stage, where potential students will check the level of knowledge demonstrated on the test, motivation, and willingness to learn.

“In 2025, more than 15,000 people from 130 countries took part in the RUDN Open Olympiad for Foreign Citizens. The winners were 1,749 people. In 2026, 650 quotas have been allocated, which will be distributed through the Olympics,” said Marina Reketz, Vice-Rector for International Affairs.

Diplomats about RUDN University

The Ambassador of the Republic of Ghana to Russia, Koma Steem Jehu-Appiah, made a speech at the round table, where he thanked RUDN for the education, skills and friendly relations he had received.

“I am confident that the cooperation that I started when I arrived in Russia as Ambassador to the Russian Federation benefits our two countries culturally and technologically, contributing to economic growth,” said Koma Steem Jehu-Appiah.

In turn, Rector Oleg Yastrebov presented the graduate with the latter’s personal file, which had been kept at the university since 1985. Oleg Alexandrovich noted that there is a characteristic of the future ambassador given by a political party in the case, and if you look at his grades, you can see that he had almost all A’s.

At the end of the meeting, representatives of Abkhazia and China thanked our university for the support provided to foreign students by the national fraternity of students, and the contribution of RUDN to training excellent specialists. The traditional round table ended on a warm and friendly note.
