Green Synthesis of Silver Nanoparticles Using Muña: A Step Toward Sustainable Nanotechnology

 Green Synthesis of Silver Nanoparticles Using Muña: A Step Toward Sustainable Nanotechnology




🌱 Green Chemistry Meets Nanotechnology

The quest for sustainable solutions in nanoparticle synthesis has found an ally in green chemistry! Using plant-based methods, this study explores how the Muña plant (Minthostachys acris) can revolutionize the production of silver nanoparticles (AgNPs). 🌿✨

🌍 Why Go Green in Nanoparticle Synthesis?

Conventional methods often involve toxic chemicals. 😷 But with green chemistry, researchers are turning to plant extracts to produce nanoparticles that are:
🌿 Environmentally Friendly
⏱️ Efficient
💰 Cost-Effective

Muña, a plant brimming with organic compounds, is leading the way in this exciting field! 🌸

🧪 How Were the Nanoparticles Made?

The process involves biosynthesis using aqueous extracts of Muña leaves. 🍃 Here’s how it’s done:

  • 🌀 Extraction: Leaves are soaked and agitated in water (0.1% concentration).
  • ⏳ Timing Matters: Extraction times ranged from 0.5 to 10 minutes.
  • ⚛️ pH Balance: Synthesis was conducted at neutral (pH 7) and slightly basic (pH 8) conditions.

Organic compounds like caffeic acid and flavonols reduced and stabilized the AgNPs, all without harmful chemicals. ✅

🔬 Characterizing the AgNPs

To understand their properties, the nanoparticles underwent thorough analysis:

  • 📡 UV-visible spectroscopy: Showed absorption peaks at 419–423 nm, confirming nanoparticle formation.
  • 🌀 DLS: Measured particle sizes between 11–200 nm.
  • 🔍 SEM: Revealed monodisperse nanospheres.
  • 🌈 LIBS: Confirmed the presence of silver in the solution.

🦠 Fighting Bacteria with Green Nanoparticles

The antibacterial potential of these AgNPs was tested against two harmful bacteria:

  • Escherichia coli
  • Staphylococcus aureus

💊 Results? The nanoparticles synthesized with 6-minute extracts showed significant bacterial inhibition, making them a promising tool in healthcare and beyond. 💪

🌟 Why It Matters

This green synthesis method demonstrates:

  • 🌿 The power of nature in advanced technology.
  • 💡 A sustainable way to produce nanoparticles with biomedical applications.
  • 🚀 A step toward reducing toxic waste in nanotechnology.

By harnessing the natural properties of Muña, we’re paving the way for a greener, healthier future. 🌎💚

Abrisa Technologies Acquires Agama Glass Technologies

SANTA PAULA, Calif. — Abrisa Technologies, a provider of custom glass optics and thin film coatings and a subsidiary of HEF Photonics, has acquired Agama Glass Technologies, a manufacturer of etched anti-glare glass and technical glass processing. The acquisition, Abrisa said, expands its manufacturing footprint and adds a vertically integrated solution for chemically etched anti-glare display glass. According to Abrisa, Clarksburg, West Virginia-based Agama operates North America’s only high-volume technical glass etching facility. Agama's flagship product, AgamaEtch, is used in high-performance display and optics applications. The company's 85,000 sq ft facility also offers precision glass fabrication, chemical strengthening, and silk-screen printing, serving markets such as avionics, defense, medical, industrial, and touchscreen displays. Combined with Abrisa Technologies’ and HEF Photonics’ thin-film coating and surface engineering capabilities, Agama's offerings wi...

How Biophotonics Is Harnessing Light for Health And Science

Fifty or so years ago French physicist Pierre Aigrain coined the term photonics as a research field whose goal was to use light to perform functions that traditionally fell within the typical domain of electronics, such as telecommunications, and information processing. Or maybe it was John Campbell who, in a letter sent to Gotthard Gunther in 1954, wrote, “Incidentally, I’ve decided to invent a new science — photonics. It bears the same relationship to Optics that electronics does to electrical engineering. Photonics, like electronics, will deal with the individual units; optics and EE deal with the group phenomena! And note that you can do things with electronics that are impossible in electrical engineering!” Naming rights aside, the field of photonics began in earnest between 1958 and 1960 with the invention of the maser and the laser. The laser diode followed during the 1970s, optical fibers and the erbium-doped fiber amplifier after that, and, pretty soon, the telecommunications...

Laser Method Enables Fast & Precise Blood Vessels in Hydrogel

Researchers from Vienna University of Technology (TU Wien) and Keio University have found a way to create artificial blood vessels in miniature organ models in a quick and reproducible manner. The method utilizes ultrashort laser pulses in the femtosecond range to write highly 3D structures into a hydrogel. In biomedical research, organs-on-a-chip are becoming increasingly important: By cultivating tissue structures in precisely controlled microfluidic chips, it is possible to conduct research much more accurately than in experiments involving living humans or animals. However, there has been a major obstacle: such mini-organs are incomplete without blood vessels. To facilitate systematic studies and ensure meaningful comparisons with living organisms, a network of perfusable blood vessels and capillaries must be created — in a way that is precisely controllable and reproducible. “We can create channels spaced only a hundred micrometers apart. That’s essential when you would like to...
