Aluminum foil as a substrate for metal enhanced fluorescence of bacteria labelled with quantum dots, shows very large enhancement and high contrast

Sultangaziyev, Alisher; Akhmetova, Aktilek; Kunushpayeva, Zhanar; Rapikov, Alisher; Olena, Filchakova; Bukasov, Rostislav (Elsevier, 2020-02-21)

Very high surface/metal enhanced fluorescence was observed for E. coli single bacteria cells labeled with composite CdSeS/ZnS quantum dots (QDs) on three substrates: aluminum foil, aluminum film and gold film. The enhancement ...
APPLICATIONS OF NOVEL SILICON AND ALUMINUM BASED SUBSTRATES FOR THE SURFACE-ENHANCED SPECTROSCOPIES: SERS AND SEF

Sultangaziyev, Alisher (Nazarbayev University School of Sciences and Humanities, 2021-05)

This Master’s thesis investigates the applicability of non-traditional substrates for surface-enhanced Raman spectroscopy and surface-enhanced fluorescence. The use of silicon wafer for sandwich SERS immunoassay and ...
DEVELOPMENT AND VALIDATION OF HYBRID BRILLOUIN-RAMAN SPECTROSCOPY FOR NONCONTACT ASSESSMENT OF MECHANO-CHEMICAL PROPERTIES OF URINE PROTEINS AS BIOMARKERS OF KIDNEY DISEASES

Gaipov, Abduzhappar; Utegulov, Zhandos N.; Bukasov, Rostislav; Turebekov, Duman; Tarlykov, Pavel; Markhametova, Zhannur; Nurekeyev, Zhangatay; Kunushpayeva, Zhanar; Sultangaziyev, Alisher (BMC, 2020-06-15)

Background Proteinuria is a major marker of chronic kidney disease (CKD) progression and the predictor of cardiovascular mortality. The rapid development of renal failure is expected in those patients who have higher level ...
HOW GAP DISTANCE BETWEEN GOLD NANOPARTICLES IN DIMERS AND TRIMERS ON METALLIC AND NON-METALLIC SERS SUBSTRATES CAN IMPACT SIGNAL ENHANCEMENT

Arbuz, Alexandr; Sultangaziyev, Alisher; Rapikov, Alisher; Kunushpayeva, Zhanar; Bukasov, Rostislav (Nanoscale Advances, 2022)

The impact of variation in the interparticle gaps in dimers and trimers of gold nanoparticles (AuNPs), modified with Raman reporter (2-MOTP), on surface-enhanced Raman scattering (SERS) intensity, relative to the SERS ...
REVIEW: APPLICATIONS OF SURFACE-ENHANCED FLUORESCENCE (SEF) SPECTROSCOPY IN BIO-DETECTION AND BIOSENSING

Sultangaziyev, Alisher; Bukasov, Rostislav (Elsevier, 2020-12)

Surface-enhanced fluorescence (SEF) is rapidly becoming one of the main spectroscopic techniques for the detection of a variety of biomolecules and biomarkers. The main reasons for this trend are the high sensitivity ...
SANDWICH SERS IMMUNOASSAY OF HUMAN IMMUNOGLOBULIN ON SILICON WAFER COMPARED TO TRADITIONAL SERS SUBSTRATE, GOLD FILM

Kunushpayeva, Zhanar; Rapikov, Alisher; Akhmetova, Aktilek; Sultangaziyev, Alisher; Dossym, Dina; Bukasov, Rostislav (Sensing and Bio-Sensing Research, 2020-08)

Likely the first application of silicon wafer as a substrate for sandwich immunoassay with Surface Enhanced Raman Scattering (SERS) detection is reported hereafter. Human immunoglobulin (hIgG) was used as a model biomarker ...
