Nanotechnology-based approaches have enabled overcoming the challenging issues such as the rapid clearance, poor solubility, and non-specific action or cellular uptake of drugs. In this study, we have evaluated the therapeutic effects of the phenolic compound, ferulic acid (FA), in the acute pancreatitis (AP) as this phenolic compound has demonstrated promising effects against the oxidative stress and inflammatory reactions. In order to overcome the poor solubility and bioavailability of FA, it was entrapped into the nanoparticles (NPs) based on the silk fibroin (SF) as a biomimetic substance. Neutrophil membrane-coated SF-NPs with appropriate capacity of FA loading and physicochemical characteristics, released FA in a controlled fashion, selectively delivered FA into the inflammatory pancreas lesion, and demonstrated protective effects against the detrimental aspects of the disease. The prepared nanoformulation by improving the pharmacological profile of FA and targeted delivery could be of therapeutic importance against the AP via suppressing the inflammation and oxidative stress.

The remarkable toughness (>70 MJ m) of silkworm silk is largely attributed to its hierarchically arranged nanofibrillar nanostructure. Recreating such tough fibers through artificial spinning is often challenging, in part because degummed, dissolved silk is drastically different to the unspun native feedstock found in the spinning gland. The present work demonstrates a method to dissolve silk without degumming to produce a solution containing undegraded fibroin and sericin.

Burns carry a large surface area, varying in shapes and depths, and an elevated risk of infection. Regardless of the underlying etiology, burns pose significant medical challenges and a high mortality rate. Given the limitations of current therapies, tissue-engineering-based treatments for burns are inevitable.

Wound bacterial infections not only impede the healing process but can also give rise to a range of serious complications, thereby posing a substantial risk to human health. Developing effective wound dressings incorporating phototherapy functionalities, specifically photothermal therapy (PTT) and photodynamic therapy (PDT), remains a critical area of research in modern wound care. Existing PTT-PDT systems often suffer from challenges such as nanoparticle aggregation and inefficient reactive oxygen species (ROS) generation, which are essential for therapeutic efficacy.

Exogenous genes are inserted into target cells during gene therapy in order to compensate or rectify disorders brought on by faulty or aberrant genes. However, gene therapy is still in its early stages because of its unsatisfactory therapeutic effects which are mainly due to low transfection efficiency of vectors, high toxicity, and poor target specificity. A natural polymer with numerous bioactive sites, good mechanical qualities, biodegradability, biocompatibility, and processability called silk fibroin has gained attention as a possible gene therapy vector.

Photolithography is the most widely used micropatterning technique at the micro- and nanoscale in device fabrication. However, traditional photoresists used in photolithography are typically nonaqueous-based toxic substances that require harsh conditions for processing, limiting the development of biofunctional and biocompatible micropatterns. In this study, a protein-based aqueous photoresist derived from chemically modified silk fibroin named SAMA, capable of achieving high-resolution micropatterning (<1.
