[PMID: 38854544 PMCID: PMC11154895 DOI: 10.1021/acsomega.4c01859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 04/23/2024] [Accepted: 04/30/2024] [Indexed: 06/11/2024]
Abstract
We present a novel colorimetric method inspired by nature's complex mechanisms, capable of selectively determining serotonin with high sensitivity. This method exploits the inherent binding affinity of serotonin with sialic acid (SA) molecules anchored to gold nanoparticles (SA-AuNPs). Upon serotonin binding, SA-AuNPs aggregate, and a characteristic red shift in the absorbance of SA-AuNPs accompanied by a dramatic color change (red to blue) occurs, readily observable even without instrumentation. The proposed method effectively eliminates interventions from potential interfering species such as dopamine, epinephrine, l-tyrosine, glucosamine, galactose, mannose, and oxalic acid. The absence of a color change with l-tryptophan, a structurally related precursor of serotonin, further confirms the high selectivity of this approach for serotonin detection. The colorimetric method has a wide linear dynamic range (0.05-1.0 μM), low limit of detection (0.02 μM), and fast response time (5 min). The limit of detection of the method is lower than other colorimetric serotonin sensors reported so far. The possible use of the proposed method in biological sample analysis was evaluated by employing a serotonin recovery assay in processed human plasma. The recoveries ranged from 90.5 to 104.2%, showing promising potential for clinical applications.

Abstract
Lung cancer (LC) is a crisis of catastrophic proportions. It is a global problem and urgently requires a solution. The classic chemo drugs are lagging behind as they lack selectivity, where their side effects are spilled all over the body, and these adverse effects would be terribly tragic for LC patients. Therefore, they could make a bad situation worse, inflict damage on normal cells, and inflict pain on patients. Since our confidence in classic drugs is eroding, chitosan can offer a major leap forward in LC therapy. It can provide the backbone and the vehicle that enable chemo drugs to penetrate the hard shell of LC. It could be functionalized in a variety of ways to deliver a deadly payload of toxins to kill the bad guys. It is implemented in formulation of polymeric NPs, lipidic NPs, nanocomposites, multiwalled carbon nanotubes, and phototherapeutic agents. This review is a pretty clear proof of chitosan's utility as a weapon in battling LC. Chitosan-based formulations could work effectively to kill LC cells. If a researcher is looking for a vehicle for medication for LC therapy, chitosan can be an appropriate choice.

Abstract
The specific interaction between cell surface receptors and corresponding antibodies has driven opportunities for developing targeted cancer therapies using nanoparticle systems. It is challenging to design and develop such targeted nanomedicines using antibody ligands, as the final nanoconjugate's specificity hinges on the cohesive functioning of its components. The multicomponent nature of antibody-conjugated nanoparticles also complicates the characterization process. Regardless of the type of nanoparticle, it is essential to perform physicochemical characterization to establish a solid foundation of knowledge and develop suitable preclinical studies. A meaningful physicochemical evaluation of antibody-conjugated nanoparticles should include determining the quantity and orientation of the antibodies, confirming the antibodies' integrity following attachment, and assessing the immunoreactivity of the obtained nanoconjugates. In this review, the authors describe the various techniques (electrophoresis, spectroscopy, colorimetric assays, immunoassays, etc.) used to analyze the physicochemical properties of nanoparticles functionalized with antibodies and discuss the main results.

Abstract
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. The preparation of nanofibers was done with the electrospinning technique. The solid state characterization and in-vitro performance assessment of nanofibers indicate the formation of uniformly interconnected nanofibers of 200-400 nm in diameter with smooth surface topography, excellent drug entrapment, and a surface pH of 5.6-6.8. The antifungal study showed that the nanofiber matrix exhibits excellent biofilm inhibition activity against several strains of Candida. Further, in-vivo assessment of nanofiber performance on C. albicans infected wounds in diabetic rats indicated accelerated wound healing efficacy in comparison to gauge-treated groups. Additionally, a higher blood flow and rapid re-epithelialization of wound tissue in the treatment group corroborated with the results obtained in the wound closure study. Overall, the developed dual-drug-loaded electrospun nanofiber mats have good compatibility, surface properties, and excellent wound healing potential, which can provide an extra edge in the management of complex diabetic wounds.

Abstract
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. As a result, developing innovative dressing materials that combat fungal infections while also providing wound healing is a viable strategy to treat infected wounds and address the issue of antibiotic resistance. Present work proposed anti-infective dressing material for the treatment of fungal strains Candida-infected diabetic foot ulcer (DFU). The nanofiber was fabricated using polyvinyl Alcohol/chitosan as hydrogel base and co-loaded with silver nanoparticles (AgNP) and luliconazole-nanoparticles (LZNP) nanoparticles, prepared using PLGA. Fabricated nanofibers had pH close to target area and exhibited hydrophilic surface suitable for adhesion to wound area. The nanofibers showed strong antifungal and antibiofilm properties against different strains of Candida; mainly C. albicans, C. auris, C. krusei, C. parapsilosis and C. tropicalis. Nanofibers exhibited excellent water retention potential and water vapour transmission rate. The nanofibers had sufficient payload capacity towards AgNP and LZNP, and provided controlled release of payload, which was also confirmed by in-vivo imaging. In-vitro studies confirmed the biocompatibility and enhanced proliferation of Human keratinocytes cells (HaCaT). In-vivo studies showed accelerated wound closure by providing ant-infective action, supporting cellular proliferation and improving blood flow, all collectively contributing in expedited wound healing.

Abstract
Targeted gemcitabine (GEB) loaded 5-N-acetyl-neuraminic acid (Neu5Ac) assembled chitosan nanoparticles (CA-NPs) were formulated by ionotropic gelation process and evaluated for physicochemical and morphological characterization, in vitro and in vivo studies in A-549 cells and lung cancer mice model, respectively. The mean diameter of GEB-CA-Neu5Ac-NPs determined by dynamic light scattering was 161.16 ± 7.70 nm with a polydispersity index (PDI) value of 0.303 ± 0.011 and its zeta potential and entrapment efficiency (%EE) were 40.3 ± 3.45 mv and 66.11 ± 1.94%, respectively. The in vitro cellular uptake studies showed that glycan receptor-targeted nanoparticles deliver significantly more amount (p < 0.001) of GEB into the A-549 lung cancerous cells than non-targeted nanoparticles. The cytotoxicity study using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay clearly demonstrated that GEB-CA-Neu5Ac-NPs have lower IC50 value (6.39 ± 3.78 µg/ml) than others groups that showed that the greater lung cancerous cells inhibition potential of targeted nanoparticles. The in vivo biodistribution of the GEB-loaded 5-N-acetyl-neuraminic acid conjugated chitosan nanoparticles was revealed that targeted nanoparticles showed higher accumulation and retention for an extended period of time due to the active targeting ability of Neu5Ac to glycan receptors. Histopathological examination showed significant recovery in the physiological architecture upon administration of targeted nanoparticles. The glycan receptor-targeted nanoparticles treated groups showed a significant decline in the number of metastatic lung epithelial cells, as compared to the untreated positive control group (p < 0.001) confirming higher anticancer efficacy of the GEB-CA-Neu5Ac-NPs.
