Here we demonstrate materials and operating conditions that allow for high-resolution printing of layers quantum dots (QDs) with precise control over thickness submicron lateral resolution capabilities use as active QD light-emitting diodes (LEDs). The shapes thicknesses the patterns exhibit systematic dependence on dimensions nozzle ink composition in ways nearly arbitrary, when exploited a fully automated tool. Homogeneous arrays QDs serve basis corresponding LEDs excellent performance....
The extracellular matrix (ECM) is a complex network of biomolecules with varying pore sizes, posing challenge for the effective penetration lipid nanoparticles. In contrast, cell-derived nanoparticles, such as exosomes, have demonstrated ability to travel distant organs, indicating their capacity penetrate ECM. Here, we designed exosome-like vesicles (ELVs) inspired by exosomes' distinct transport phenomena. Specifically, integrated three exosomal components (anionic lipid, cholesterol, and...
RNAi technology is currently experiencing a revival due to remarkable improvements in efficacy and viability through oligonucleotide chemical manipulations and/or via their packaging into nanoscale carriers. At present, there no FDA-approved system for siRNA humans. The design of the next generation carriers requires deep understanding how nanoparticle's physicochemical properties truly impart biological stability efficiency. For example, we now know that nanoparticles need be sterically...
Bioresorbable drug release platforms offer advanced treatment for hormone imbalances, malignant cancers, and diabetic conditions.
On-demand, localized release of drugs in precisely controlled, patient-specific time sequences represents an ideal scenario for pharmacological treatment various forms hormone imbalances, malignant cancers, osteoporosis, diabetic conditions and others. We present a wirelessly operated, implantable drug delivery system that offers such capabilities form undergoes complete bioresorption after engineered functional period, thereby obviating the need surgical extraction. The device architecture...
Screening for prostate cancer relies on the serum prostate-specific antigen test, which provides a high rate of false positives (80%). This results in large number unnecessary biopsies and subsequent overtreatment. Considering frequency there is critical unmet need precision screening cancer. Here, we introduced urinary multimarker biosensor with capacity to learn achieve this goal. The correlation clinical state sensing signals from multimarkers was analyzed by two common machine learning...
The rapid development of messenger RNA (mRNA) vaccines formulated with lipid nanoparticles (LNPs) has contributed to control the COVID-19 pandemic. However, mRNA have raised concerns about their potential toxicity and clinical safety, including side effects, such as myocarditis, anaphylaxis, pericarditis. In this study, we investigated trehalose glycolipids-containing LNP (LNP S050L) reduce risks associated ionizable lipids. Trehalose glycolipids can form hydrogen bonds polar biomolecules,...
Bladder cancer, when diagnosed at an advanced stage, often necessitates inevitable invasive intervention. Consequently, non-invasive biosensor-based cancer detection and AI-based precision screening are being actively employed. However, the misclassification of patients as normal-referred to false negatives-remains a significant concern, it could lead fatal outcomes in lifespan. Moreover, while ensemble techniques such soft voting other methods can improve model accuracy reduce...
The success of gene technologies hinges on our ability to engineer superior encapsulation and delivery vectors. Cubosomes are lipid-based nanoparticles where membranes, instead enveloping into classic liposomes, intertwine complex arrays pores well-ordered in a cubic lattice. These encapsulate large contents siRNA compared liposomal analogue. Importantly, the membranes that form cubosomes have intrinsic fusogenic properties promote fast endosomal escape. Despite great potential, traditional...
Repeatedly applied nanoconfinement of [HMIM] EtSO<sub>4</sub> between mica surfaces induces a long-range liquid-to-solid transition that remains after confinement has been removed.
Aramid nanofibers (ANFs), typically produced by exfoliating aramid microfibers (Kevlar) in alkaline media, exhibit excellent mechanical properties and have therefore attracted increased attention as nanoscale building blocks. However, the preparation of involves laborious hazardous processes, which limits industrial-scale use ANFs. This work describes a facile direct monomer-to-ANF synthesis via an as-synthesized intermediate low-molecular-weight poly(p-phenylene terephthalamide) (PPTA)...
Polypeptide micelles are widely used as biocompatible nanoplatforms but often suffer from their poor structural stability. Unimolecular polypeptide can effectively address the structure instability issue, synthesis with uniform and well-controlled desired sizes remains challenging. Herein we report convenient preparation of spherical unimolecular through dendritic polyamine-initiated ultrafast ring-opening polymerization N-carboxyanhydrides (NCAs). Synthetic polypeptides exceptionally high...
SARS-CoV-2 variants are of particular interest because they can potentially increase the transmissibility and virulence COVID-19 or reduce effectiveness available vaccines. However, screening is a challenge biosensors target viral components that mutate. One promising strategy to screen via angiotensin-converting enzyme 2 (ACE2), virus receptor shared by all known variants. Here we designed highly sensitive portable biosensor based on receptor. We chose dual-gate field-effect transistor...
With reference to our previous surface-force study on 1-hexyl-3-methylimidazolium ethylsulfate ([HMIM] EtSO4) using an extended surface forces apparatus, which showed ordered structure within the nanoconfined dry ionic liquid (IL) between mica surfaces that up ∼60 nm from surface, this work focuses influence of environmental humidity bulk, interfacial and [HMIM] EtSO4. Infrared spectroscopy rheometry reflect changes in chemical physical properties bulk IL due uptake water when exposed...
Significance Lipids self-assemble in water into diverse polycrystalline mesophases. The swelling capacity of these superstructures is finite, specific, and traditionally dictated by lipid composition. Bicontinuous cubic phases have tremendous potential drug delivery protein crystallization. However, limited caps unit cells at dimensions too small to encapsulate many drugs most proteins. In this work, we discovered that bicontinuous phase not solely determined Self-assembly conditions yield...
Multilamellar membranes are important building blocks for constructing self-assembled structures with improved barrier properties, such as multilamellar lipid vesicles. Polymeric vesicles (polymersomes) have attracted growing interest, but polymersomes much less explored. Here, we report the formation of polypeptide unprecedented densely packed multilayer membrane poly(ethylene glycol)-block-poly(γ-(4,5-dimethoxy-2-nitrobenzyl)-l-glutamate) (PEG-b-PL), an amphiphilic diblock rod-coil...
Abstract Enhanced force transmission to mechanophores is demonstrated in polymer nanocomposite materials. Spiropyran (SP) that change color and fluorescence under mechanical stimuli are functionalized at the interface between SiO 2 nanoparticles polymers. Successful activation of SP confirmed both solution solid states. Compared with SP‐linked bulk polymers, interfacial induces greater conversion its colored merocyanine form also significantly decreases threshold tension. Experimental...
