What Is Amnium Technologies? A Guide to Their Nanoparticle Products

If you’ve searched “Amnium,” you’ve probably landed on a scattering of directory listings on IndiaMART, TradeIndia, or ExportersIndia and wondered who’s actually behind them. Amnium Technologies Pvt. Ltd. is a small, Pune-based manufacturer of antimicrobial metal nanoparticles, most notably silver and copper, along with related nanomaterials used in coatings, inks, and research. Here’s what the company makes, how its products are typically used, and what to check before you buy.

Amnium Technologies at a Glance

Amnium Technologies was established in 2018 and is headquartered in Kothrud, Pune, Maharashtra. It’s a private limited company with fewer than 20 employees, run under the direction of Jaydeep Deshpande. The firm operates in a genuinely niche corner of the chemicals industry: engineered metal nanomaterials, sold mostly to industrial buyers, formulators, and research labs rather than to consumers.

Unlike large multinational chemical suppliers, Amnium sells primarily through B2B marketplaces. Its listings show up across IndiaMART, TradeIndia, and ExportersIndia, where it’s identified as a manufacturer, exporter, and supplier of nanomaterials for R&D and industrial use.

What Products Does Amnium Technologies Make?

The company’s catalog centers on a handful of related product lines:

• Silver nanoparticles (AgNPs): Offered in powder and colloidal (water-dispersible) forms, in several particle sizes, including roughly 10 nm, 50–60 nm, and 100–200 nm, at different purity grades (technical, analytical, and “biotech” grade)
• Copper and copper oxide nanoparticles: Used for similar antimicrobial and conductive purposes, often at a lower cost than silver
• Silver and copper nanowires: A thinner, wire-shaped nanostructure used in transparent conductive films and flexible electronics
• Silver conductive ink and paste: Formulated for printed electronics, circuit repair, and conductive coatings
• Magnetic and iron oxide nanoparticles: Plus smaller-volume items like nickel nanoparticles

Pricing on public listings ranges from roughly ₹100 to ₹400 per gram, depending on grade, particle size, and dispersion type, with minimum order quantities as low as 10 grams for lab-scale buyers.

Why Silver and Copper Nanoparticles Are Used as Antimicrobials

Silver has a long history as an antimicrobial agent, and nanoscale silver amplifies that effect. Because silver nanoparticles have a huge surface area relative to their size, they release silver ions more readily, which disrupts bacterial cell membranes and interferes with how pathogens function. A 2022 review in the veterinary science journal Pashudhan Praharee notes that silver nanoparticles show broad activity against bacteria, fungi, and viruses, and that researchers continue refining particle size and shape to improve stability and effectiveness. Copper nanoparticles work on a related principle and are often used as a lower-cost alternative or complement to silver.

That’s the underlying science behind why manufacturers like Amnium market these materials for antimicrobial composites, wound-care formulations, coatings, and paints, though it’s worth noting that antimicrobial claims for any finished product still depend on how the nanoparticles are formulated, tested, and regulated in the end application.

Who Buys From a Company Like Amnium?

Based on its product mix, Amnium’s customer base likely spans a few overlapping groups:

1. Formulators and manufacturers building antimicrobial coatings, paints, textiles, or packaging
2. Electronics and printed-circuit companies sourcing silver conductive ink or nanowires for flexible or transparent conductors
3. University and industrial R&D labs buying small, precisely characterized batches for testing and experimentation
4. Wound-care and medical device formulators exploring silver’s antibacterial properties, subject to the relevant regulatory approvals for their region

How Amnium Compares to Other Indian Nanoparticle Suppliers

India has a growing cluster of small and mid-sized nanomaterial manufacturers, many of which, like Amnium, sell through the same B2B marketplaces. Competitors visible on the same directories include firms such as Reinste Nanoventures, Nano Wings, and Techinstro, among others. Most compete on similar terms: particle size options, purity grade, price per gram, and minimum order quantity. If you’re evaluating suppliers, it’s worth comparing certificates of analysis, particle size distribution data, and batch consistency rather than price alone, since nanoparticle performance can vary meaningfully between suppliers even at the same nominal purity.

Questions to Ask Before Ordering

A few practical checks can save you a bad batch:

• Ask for a certificate of analysis showing particle size, size distribution, and purity for the specific lot you’d receive
• Confirm whether the material is powder or a pre-dispersed colloid, since this affects handling and shelf life
• Check redispersibility if you’re buying powder for a liquid formulation
• Clarify packaging (reagent bottle, vacuum-sealed, etc.) and shipping conditions, especially for international orders
• Ask about typical lead times, since small manufacturers often produce to order rather than holding large stock
