Bacterial cellulose nanoparticles as a sustainable drug delivery platform for protein-based therapeutics

Abstract

Sustainable nanomedicine is an emerging field aiming to address the challenges of scalability, reproducibility, thermal stability, and excessive waste generation for nanotherapeutic manufacturing. Bacterial cellulose (BC) fibers have the potential...

Green synthesis of iron-doped graphene quantum dots: an efficient nanozyme for glucose sensing

“…2b) indicated the presence of abundant oxygen and nitrogen-containing functional groups on the surface of the GQD-based nanoparticles. These functional groups included –COOH (CO stretch around 1760–1690 cm −1 , C–O stretch around 1320–1210 cm −1 ), –OH (O–H stretch around 3300–2500 cm −1 , O–H bend from 1440–1395 and 950–910 cm −1 ), and –NH 2 (N–H stretch around 3400–3250 cm −1 , N–H bend around 1650–1580 cm −1 , C–N stretch (aromatic amines) around 1335–1250 cm −1 , N–H wag from 910–665 cm −1 ) groups, 74,75 These functional groups contribute to the colloidal stability of FeN/GQDs. Peaks around 680, 520, and 440 cm −1 corresponding to Fe–O bonds were barely detected, indicating a limited content of oxidized iron in the sample.…”

Synthesis of Transparent Bacterial Cellulose Films as a Platform for Targeted Drug Delivery in Wound Care

“…As depicted in Figure 7, the FTIR spectrum of the pure BC film reveals several distinctive peaks indicative of its molecular structure. A notable peak at 2894 cm −1 corresponds to the CH stretching vibrations at the C-6 position, suggesting the presence of alkane or alkene functional groups within the cellulose structure [21]. The spectrum also shows a range of peaks between 1427 and 1315 cm −1 , which represent various functional groups and vibrations inherent to BC.…”

“…BC's versatility allows for easy tailoring into different formats, such as films, particles, hydrogels, and fibers, making it highly suitable for integration into various wound dressings [21][22][23]. Its properties can also be tailored to address specific needs for various types of wounds.…”
