Fabrication of lipid-modified drug nanocrystals loaded injectable hydrogel for breast cancer therapy.

The current study includes the design of soluplus stabilized, lipid-coated, and fucoidan-oleylamine conjugate modified paclitaxel nanocrystals. The nanocrystals (Lipid-NCs) were about 100 nm, homogeneous, stable and showed improved drug release compared to pure PTX. The nanocrystals were subsequently loaded in an in situ gel-forming hydrogel for the intratumoral injection.

Formulation and evaluation of cetuximab functionalized phospholipid modified nanocrystals of paclitaxel for non-small cell lung cancer therapy.

Present work aims to prepare Soluplus stabilized, phospholipid-modified, and cetuximab-conjugated paclitaxel nanocrystals (NCs) as stable nanocarriers for targeted drug delivery. The NCs, prepared using concurrent antisolvent precipitation cum cold crystallization method followed by probe sonication, were found to be monodispersed particles with sub-200 nm size. The microscopic analysis uncovered rod and spherical anisotropy for Soluplus stabilized (PTX-NCs) and phospholipid modified (Lipid/PTX-NCs) nanocrystals, respectively.

Hyaluronic acid-oleylamine and chitosan-oleic acid conjugate-based hybrid nanoparticle delivery via. dissolving microneedles for enhanced treatment efficacy in localized breast cancer.

Microneedle technology offers a minimally invasive treatment strategy to deliver chemotherapeutics to localized tumors. Amalgamating the surface functionalized nanoparticles with microneedle technology can potentially deliver drugs directly to tumors and subsequently target cancer cells via, overexpressed receptors on the cell surface, thereby enhancing the treatment efficacy while reducing side effects. Here, we report cetuximab anchored hyaluronic acid-oleylamine and chitosan-oleic acid-based hybrid nanoparticle (HA-OA/CS-OA NPT)-loaded dissolving microneedles (MN) for targeted delivery of cabazitaxel (CBT) in localized breast cancer tumor.

Lipid-coated nanocrystals of paclitaxel as dry powder for inhalation: Characterization, in-vitro performance, and pharmacokinetic assessment.

Background: Nanocrystals can be produced as a dry powder for inhalation (DPIs) to deliver high doses of drug to the lungs, owing to their high payload and stability to the shear stress of aerosolization force. Furthermore, lipid-coated nanocrystals can be formulated to improve the drug accumulation and retention in lung.

Objective: The present work involved the fabrication of paclitaxel nanocrystals using hydrophilic marine biopolymer fucoidan as a stabilizer.

Biopolymer-based tumor microenvironment-responsive nanomedicine for targeted cancer therapy.

Nanomedicine has opened up new avenues for cancer treatment by enhancing drug solubility, permeability and targeted delivery to cancer cells. Despite its numerous advantages over conventional therapies, nanomedicine may exhibit off-target drug distribution, harming nontarget regions. The increased permeation and retention effect of nanomedicine in tumor sites also has its limitations, as abnormal tumor vasculature, dense stroma structure and altered tumor microenvironment (TME) may result in limited intratumor distribution and therapeutic failure.

Fabrication of gelatin coated polycaprolactone nanofiber scaffolds co-loaded with luliconazole and naringenin for treatment of Candida infected diabetic wounds.

The current study focuses on the development of gelatin-coated polycaprolactone (PCL) nanofibers co-loaded with luliconazole and naringenin for accelerated healing of infected diabetic wounds. Inherently, PCL nanofibers have excellent biocompatibility and biodegradation profiles but lack bioadhesion characteristics, which limits their use as dressing materials. So, coating them with a biocompatible and hydrophilic material like gelatin can improve bioadhesion.

Formulation and characterization of polyvinyl alcohol/chitosan composite nanofiber co-loaded with silver nanoparticle & luliconazole encapsulated poly lactic-co-glycolic acid nanoparticle for treatment of diabetic foot ulcer.

Chronic wounds are prone to fungal infections, possess a significant challenge, and result in substantial mortality. Diabetic wounds infected with Candida strains are extremely common. It can create biofilm at the wound site, which can lead to antibiotic resistance.

Fabrication of dual drug-loaded polycaprolactone-gelatin composite nanofibers for full thickness diabetic wound healing.

Design of moxifloxacin and ornidazole co-loaded polycaprolactone and gelatin nanofiber dressing for diabetic wounds. The composite nanofibers were prepared using electrospinning technique and characterized for drug release, antibacterial activity, laser doppler and wound healing. The optimized nanofiber demonstrated an interconnected bead free nanofiber with average diameter <200 nm.
