Tailoring the Properties of Functional Materials With N‐Oxides

open access: yesAdvanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Harnessing Next‐Generation 3D Cancer Models to Elucidate Tumor‐Microbiome Crosstalk

open access: yesAdvanced Healthcare Materials, EarlyView.
Centralizes the microbiome within 3D tumor‐microbiome model platforms, including spheroids, organoids, 3D‐bioprinted constructs, and microfluidic chips, each enabling structured host‐tumor‐microbe studies. These systems support bacterial colonization, facilitating investigation of microbial impacts on tumor growth, immunity, and therapy. The microbiome

Natural Sweetener Stevioside‐Based Dissolving Microneedles Solubilize Minoxidil for the Treatment of Androgenic Alopecia

open access: yesAdvanced Healthcare Materials, EarlyView.
This study addresses limitations of minoxidil (MXD) in treating androgenetic alopecia by using stevioside (STV) as a solubilizing agent and microneedle (MN) material. STV enhanced MXD's solubility and skin absorption, leading to improved drug delivery and significant hair regrowth in animal models, demonstrating strong potential for AGA treatment ...

Toward Strengthened Regulation of PFAS in South Korea: Health Risks, Global Standards, and Policy Recommendations [PDF]

open access: yes대한환경공학회지
Per- and polyfluoroalkyl substances (PFAS) are widely used not only in consumer products but also in semiconductor manufacturing due to their exceptional resistance to heat, water, and oil, which stems from the strong covalent bonds between carbon and ...

Carcinogenic Mycotoxins*

open access: yes, 2010
Mycotoxins are metabolites of molds considered to be a major risk factor affecting human and animal health. It is estimated that 25% of the world’s crop production is contaminated with mycotoxins. Mold contamination occurs extensively in fields and is particularly severe in tropical countries.
