Nanomaterials are materials with special properties at least one dimension in the three-dimensional space (1 mm 100 nm), or composed of nanostructural units, which is regarded as "one of the most important strategic high-tech materials in the 21st century". Because of its structural particularity and extremely unstable state in thermodynamics, nanomaterials have special properties such as small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect. As well as many physical and chemical properties that traditional materials do not have, such as high chemical activity, strong adsorption, special catalysis, and so on. Nanomaterials and novel engineered nanotechnology offer great potential to improving the quality of life when used in applications across a variety of industries and consumer products. Today, it is widely used in medicine, manufacturing, materials, communications, biology, environment, energy, food and other fields.
To realise the full potential of your nanomaterial products, it is vital to understand the unique properties of these materials and to address potential safety or risk concerns for human health and the environment. Alfa Chemistry supports our clients' nanotechnology innovation with nanomaterial chemical testing, risk assessment and safety consulting.

Techniques for safety testing of nano products
Transmission Electron Microscope (TEM)
Transmission Electron Microscope (TEM) is an instrument that can observe nanoscale materials. It has a higher resolution and magnification power compared to conventional optical microscopes. TEM is composed of infrared ray transmission and electron diffraction technologies. Through the microscopic images of the electron microscope, information about the morphology, size, and structure of nanomaterials can be obtained.
Atomic Force Microscope (AFM)
Atomic Force Microscope (AFM) is a high-resolution microscope that measures changes in the Martini curvature of a sample surface by scanning the sample surface. The AFM can be used to measure a variety of samples, including solid, liquid, and gaseous materials, and can provide detailed information about the surface morphology and roughness of nanomaterials.
X-Ray Diffraction (XRD)
X-Ray Diffraction (XRD) is a technique used to study the crystal structure of materials. Through the detection and recording of X-rays, we can obtain information about the crystal structure of materials, and thus understand the crystal structure and crystal size of nanomaterials. XRD is widely used in the study of the structure and properties of nanomaterials.
UV-Vis Absorption Spectroscopy
UV-Vis absorption spectroscopy is a commonly used tool for analyzing the visible chemical properties of nanomaterials. It determines the absorption intensity of a sample solution to visible and ultraviolet light, obtaining the absorption spectrum of the sample. By analyzing the position and relative intensity of the absorption peaks, information about the wavelength of light absorbed, concentration, and particle size of nanomaterials can be obtained.

Safety Assessment of Nanoparticles in Food
Wang, Mengjie, et al. Nano Today 39 (2021): 101169.
Nanoparticles (NPs) have had a groundbreaking impact on human life, and due to their unique properties, they have been widely applied in many fields, including electronics, optics, chemistry, food, biology, and medicine. In the food industry, nanotechnology has been used in the production, processing, storage, and distribution of food, and nano-sensors have been used to detect pathogens or contaminants in food, thereby improving food safety. NPs in food include those used in food processing, food packaging, and food additives, and are used for purposes such as antimicrobial activity, color improvement, and increasing process stability.
Intentionally added NPs in ingested foods and NPs that migrate from packaging are important sources of human exposure to NPs. Some researchers have found that ingestion of NPs may cause biological effects such as DNA damage, protein denaturation, and the induction of oxidative stress, which highlights the importance of attention to the use of NPs in food. Some countries and international organizations have proposed regulatory requirements for NPs in food.
Predicting Potential Toxicity of Carbon Nanomaterials
Esimbekova, Elena N., et al. Toxicology in Vitro 45 (2017): 128-133.
Multiple studies have demonstrated that carbon nanotubes (CNTs) exhibit cytotoxicity and genotoxicity. Additionally, CNTs can amplify the toxicity of other pollutants. Assessing the toxicity of commercial CNT formulations is crucial, as they may have negative impacts on biological entities during manufacturing and use.
A bioluminescence enzyme inhibition assay was used to predict the potential toxicity of carbon nanomaterials (CNMs), including single-walled and multi-walled carbon nanotubes (SWCNTs and MWCNTs) as well as aqueous fullerene C60 (C60HyFn) solutions.
How do you manage airborne containment and occupational safety when handling sub-micron or potentially respirable fine particulate materials?
All fine-particulate and sub-micron powders are handled within dedicated high-efficiency particulate air (HEPA) filtered negative-pressure containment hoods and gloveboxes to ensure total operator protection and prevent cross-contamination.
What is the standard timeline for safety dossier verification, and can expedited reviews be scheduled for regulatory filing deadlines?
Standard safety evaluation and reporting cycles take 10 to 15 business days. For urgent regulatory submissions or safety data sheet updates, expedited processing tracks can be arranged to prioritize dedicated instrument time.
Are your evaluation frameworks aligned with international regulatory bodies and global harmonization guidelines?
All evaluation protocols strictly adhere to international harmonization frameworks, including OECD test guidelines for manufactured nanomaterials and relevant ISO technical specifications, ensuring full global regulatory acceptance.
How do you ensure data consistency across multiple manufacturing batches submitted over a long-term R&D or commercial scale-up contract?
Each long-term project utilizes a dedicated lead scientist who maintains fixed instrument parameters, standardized dispersion protocols, and rigorous tracking logs to ensure absolute longitudinal data comparability across every production lot.
What level of technical support or data interpretation is provided if a safety parameter falls outside our targeted compliance threshold?
Every borderline or unexpected safety outcome includes a collaborative review session with our senior toxicologists and material scientists to analyze raw aggregation metrics, stability states, and potential matrix interference factors.
⭐⭐⭐⭐⭐
"We needed rapid particle behavior verification for a novel surface-modified powder before a major European regulatory submission. Their team turned around the compliance data within ten days, helping us iron out subtle agglomeration inconsistencies before final filing."
⭐⭐⭐⭐⭐
"The rigor of their safety documentation is exceptional. Their technical staff worked closely with our quality assurance team to align testing milestones with our internal safety data sheet updates, making the whole compliance audit completely seamless."
